Cisco all but kills Cius tablet computer

Cisco discontinues Cius investment and development in the face of BYOD, cloud computing

Cisco is slowly killing off its Cius business tablet less than a year after it started shipping.

The Android-based collaboration tool, which featured a 7-inch touchscreen and was not intended to challenge more consumer-oriented tablets such as the Apple iPad, fell victim to the BYOD trend and cloud computing, Cisco said in a blog post.

The post, authored by OJ Winge, senior vice president of Cisco's TelePresence Technology Group, states that Cisco will discontinue investment and development of the tablet, which we reviewed in February.

NOT TODAY; OR EVER? 10 Compelling Apps for Cisco Cius

"... 95% of organizations surveyed allow employee-owned devices in some way, shape or form in the office, and, 36% of surveyed enterprises provide full support for employee-owned devices. These stats underscore a major shift in the way people are working, in the office, at home and on-the-go, a shift that will continue to gain momentum.

"Based on these market transitions, Cisco will no longer invest in the Cisco Cius tablet form factor, and no further enhancements will be made to the current Cius endpoint beyond what's available today. However, as we evaluate the market further, we will continue to offer Cius in a limited fashion to customers with specific needs or use cases," the post states.

Cisco will instead "double down" on software offerings like its Jabber and WebEx products for more popular tablets and smartphones supporting a variety of operating systems, the blog states. Cisco unveiled a version of Jabber for the iPad at the Enterprise Connect conference earlier this year.

"We will leverage key learnings and key collaboration experiences native to Cius in our other collaboration products," Winge states in his post.

Cisco has been discontinuing disappointing products over the past year, specifically in consumer-oriented collaboration. It killed its Flip pocket videocam and its umi home TelePresence unit.

According to Network World's Cius review, the tablet was only available through the Cisco partner network. It cost less than $750 for an endpoint and less than $350 for a media station, for a total of under $1,100.

Market timing played a key role in Cius' demise, according to Ted Schadler of Forrester Research. As Cisco was conceiving, developing and preparing to launch Cius into the enterprise, corporate workers were already bringing their iPads to work.

"As you look at Cisco's business and portfolio, did (offering a tablet endpoint) make sense at this point in time?" Schadler asked. "There had been three Christmases of CEOs bringing their iPads to work."

There's no longer a question of what tablet enterprises will use at work; it's not a question of how to support it, Schadler said.

"Now the focus is around collaboration tools," he said. "All Cisco needs is a client on an iPad, not an actual device."

And with the exploding trend of BYOD, the business case of developing dedicated hardware sitting on an executive's desk becomes "much less interesting," Schadler says. "Cisco should be end-point agnostic, focusing instead on integration in the back-end."

Cellphone vibration syndrome and other signs of tech addiction

New book, iDisorder, looks at the dangers and offers advice for dealing with obsession

Computerworld - It turns out that the phantom cellphone vibration syndrome is fairly common. Ask around. See if you can find someone who believed the smartphone in their pocket was vibrating but found when they checked, there was nothing new. No call. No text.

There's a growing body of research on phantom vibrations and many of the other problems associated with technology obsession, all of which is explored by Larry Rosen, a professor of psychology at California State University, Dominguez Hills, in his new book, iDisorder.

Rosen, who earned his bachelors degree in mathematics before getting a Ph.D in psychology, examines technology's impact on our lives. His book, which combines the latest research with his own experience, anecdote and observation, warns about obsessive technological use and offers practical advice for keeping tech at bay.

In this interview, Rosen talked about some of the issues associated with unhealthy, or least unreasonable, levels of tech obsession.

What is iDisorder or technology addiction? Is it obsessive compulsive disorder, narcissism, depression, anxiety - none of this or all of the above? iDisorder is any psychological disorder that appears to be either caused by or potentially exacerbated by your relationship with media and technology. But, in fact, it's all of the ones you mentioned. Interacting with our technology can make us display signs and symptoms of everything ranging from depression to mania to narcissism to voyeurism - you name it. The research is all showing that it appears that these kinds of technologies can, unless we're watching what we're doing, lead to these kinds of issues.

If I check my cell phone every few minutes, what does that indicate? I would want to know what you are doing and what you are feeling when you do that. If you pick up your phone and check your text messages, and you go 'I got to text right back to this person,' I would suggest that what you're feeling is anxiety about not being able to check in. That's one of the underlying issues of obsessive compulsive behaviors. If you got on your phone every couple of minutes and I saw you make this big smile and say 'I got an email from an old friend and it felt so good,' then I would say that it's probably an addictive kind of behavior. It's that split between a level of addiction, meaning we're trying to get pleasure, versus our level of obsession or compulsion, meaning we're trying to reduce our anxiety.

Talk about the phantom vibration syndrome, where it feels as if the cell phone is vibrating but it isn't. Why does this happen? We're just starting to see research on this. I think it's a fascinating phenomenon. I think it comes again from anxiety. Our body is always in waiting to anticipate any kind of technological interaction, which usually comes from a smartphone. With that anticipatory anxiety, if we get any neurological stimulation, our pants rubbing against our leg for example, you might interpret that through the veil of anxiety, as 'Oh, my phone is vibrating."

And this syndrome is fairly common? Yes, I have not found anybody whom I've talked to, particularly males, because they carry their phone in their pocket, who can admit that it has never happened. There are a lot of people who say they are patting their pocket all day long.

Are phantom cell phone vibrations a reason for worry? The worry part comes from this: Is it overwhelming anxiety and is that anxiety getting in the way of anything else in your life? Most of the people will report that what it does is it gets in the way of their social relationships, because they are constantly focusing on reducing the anxiety about what they're missing out on their phone. At dinner, they're not paying attention to their family and kids. When they go out, they are not paying attention to a movie because they are always on edge and worried. If they are at a family gathering they are always checking their phone constantly. If it's that severe, then it's time to re-conceptualize what you are doing.

Is there a metric that tells you whether you are overusing information technology, or is it only a problem if it interferes with your social interactions? If it interferes with a lot of things -- your social interactions, your work product and your family responsibilities - those are the kinds of signs that you always look for in addiction and compulsive behavior.

How do I recognize this problem in the workplace? You recognize it in co-workers who can't go more than five minutes at a meeting without checking their phone. You recognize it in co-workers who get constantly distracted in the middle of a task, and the distraction usually comes from an email or text, or an internal need to check something on the Web. It really comes down to the business world as sort of rudeness, or inattentiveness, or lack or productivity or reduced productivity.

Are there steps managers can take to mitigate it in the workplace? Absolutely. What I think managers need to do is the following: If you are having problems at your meetings, which most managers are because your staff constantly has their Blackberries, iPhones, laptops and iPads there, and you know that they aren't just taking notes, what you need to be doing is something I call a tech break. This means that everybody brings their technology to the meeting, and gets one minute to two minutes to check in with your technology, and then you turn it off and upside down in front of you. And usually starting after 15 minutes of meeting, there is another one to two minute tech break, and then 15 minutes of more meeting and then another tech break. This starts to train your staff that the downside of not checking in every five seconds isn't as bad as they thought. Eventually you can lengthen the time without breaks to 20 minutes, to 25 and to 30 minutes - potentially 30 minutes. I've never seen anybody get it longer than 30.

Is this something businesses are beginning to do formally? Absolutely. It takes some training because their staffs are so hooked [into] these devices that it's no immediate success, but eventually people get it.

Are people who work in information technology at greater risk of developing problems in this area? No, I don't think so. I think everybody is. On some level, software developers may even have an easier time, because they have a bit more focus or more need to focus. But I can honestly say the research shows that software developers focus about three to five minutes before they switch tasks, and that's about what we find with students and medical students studying. I think we're at the point where we carry something in our pockets that is more powerful than any of us ever imagined.

A lot of companies are developing wired workplaces, in the sense that employees can get access to their work regardless of whether it's a company-owned device or a personal smartphone. Won't the bring-your-own-device (BYOD) push exacerbate the problem? I do believe it probably will. I think it's (BYOD) a good idea. Businesses are starting to realize that it's nice to have a dedicated Blackberry just for your work, but it's also nice to have your employees to be on 24-by-7 because they are carrying the device they're using. I do think that's going to be a problem because then you're multiplying it by two, your device is both your personal device and business device so there is twice as much free-floating anxiety.

How do you counterattack that? There are two things you can do. You don't have to carry your device 24-by-7. What I suggest is you develop your own tech break. About every couple of hours find one way to get away from all of it, phones, computers, everything - for 10 to 15 minutes. You do what neuroscientist call 'resetting your brain.' There are tons of activities that we know reset your brain. Taking a walk in nature, looking at clouds, looking at a picture book (not on your computer), exercising for a few minutes, laughing, talking to somebody, speaking a foreign language, playing a musical instrument. Our brain is at a constant, high-activation level and we need time to let it mellow, rest and reset, so then we can better process the information.

A lot of people use LinkedIn and Facebook for professional as well as social reasons, but you argue that the reliance or heavy use of these platforms can lead to problems. Why is that? First, let me say that I'm a fan of social media. I find it an amazingly powerful tool. Having said that, I think that the way social media is right now, it is promoting obsessive behaviors, it is promoting the constant need to check in. I am the worst at this. I am constantly checking in to see if there are comments on my site, because I want to jump on them. I am constantly checking in on Facebook, and one of the things that I have had to do is moderate this kind of behavior. Social media is intensely compelling.

Are there societal dangers? The major societal issue is not about the social media. The social media research tends to be coming out as flipping to the positive side. We are getting more (from social media) than we might be losing. My concern is smartphones, which I refer to as WMDs (wireless mobile devices) but I think they are also potential weapons of mass destruction. Where I see the problem is in two situations. One is in the family, the other in gatherings of friends, where you are spending too much time checking your phone and responding to things on your phone. I don't care if you claim you are multitasking. You cannot be attending to a text message and getting what your friend across the table in the restaurant is telling you completely. You might get the words, but you're not getting the context, the emotions and the feelings. You're not really paying attention. The same thing happens in the family. I see these devices as being very divisive to the family unless we set very clear guidelines about when they are acceptable and when they are not. As soon your kid gets an iPhone you may as well be talking to him about the right time use it and the wrong time.

Facebook IPO stumbles out of the gate

Social network's stock price wavers in first hours of trading

The first hours of the social networking company's IPO got off to a shaky start today with the share price wavering around the $40 mark, never gaining the astronomical momentum that had been anticipated by many. Shortly after 2 p.m. ET, the stock price was hovering just under $41, less than $3 above its initial share price.

"It's certainly not flying to unprecedented levels," said Zeus Kerravala, an analyst with ZK Research. "This underscores the thesis that many investors are taking a wait-and-see approach."

He added that while many people may be surprised Facebook's stock price hasn't taken off yet, they really shouldn't be.
"I think it's surprising a lot of people, but I think it should have been expected," said Kerravala. "There are a lot of questions about Facebook.... How are they going to monetize mobile? Can [CEO Mark] Zuckerberg run a public company?"

Twenty-eight year-old Zuckerberg started the day by ringing the Nasdaq opening bell from company headquarters in Menlo Park, Calif.

After that, though, there were a few hitches.

Trading was supposed to start at 11 a.m. ET, but the Nasdaq delayed it by about half an hour in order to handle the flood of buy and sell orders that were coming through for Facebook's stock.

Once trading actually began, the stock started out strong, trading at $42 per share, $4 above the official offering price of $38 the company set Thursday.

However, instead of rising from there, Facebook's share price began to fizzle, and dropped to below $39 just 20 minutes after trading began. Once the price hit $38, about 10 to 15 minutes later, the company's underwriters stepped in to bolster it and hold the price floor at $38, reported the Wall Street Journal.

TV commentators and online headlines began using words like "underperform" and "disappointing."

Ezra Gottheil, an analyst with Technology Business Research, said people may be jumping the gun. He contends that Facebook's stock price is hovering around where it started this morning because it was priced appropriately.

"I can say that if your IPO doesn't go up or down very much, then you priced it right," he added. "At this point, it's all about perception and expectation. The stock price is just a noise meter."

Regardless of the ups and downs the stock is going through today, there's been a huge amount of interest and excitement around the event.

As trading began, people were standing around Times Square in New York City, staring up at giant screens showing Facebook's stock numbers. At the same time, Twitter momentarily staggered under the crush of tweets about the IPO.

As noteworthy as this day has been for many in the financial and tech industry, it's been a tough day for other social networking companies.

The Wall Street Journal reported soon after trading of Facebook's stock began that LinkedIn's stock price was down 2.6% and Groupon was down 6%. Pandora also was down, dropping 5%.

Zynga, though, might have fared the worst. The online gaming company's share price toppled a full 13%, landing at $7.17, according to MarketWatch . Trading on that stock was halted, later reinstated, then halted for a second time.
