I just came across Twitter Peek, a handheld device that operates off its own mobile network that gives you 100% dedicated access to your Twitter account all the time. For $199 (or $99 with 6mos and $7.95/mo afterward) you too can solidify your tweeting addiction.Seriously though, I like the concept of a twitter device. Unfortunately, in today’s world, carrying around multiple devices is not cool anymore. Since you can only tweet from it, it truly is a mono-tasker. I do like the concept of having dedicated access to Twitter for a flat monthly rate. Still, I wonder how big the market is for this product. iPhone users aren’t going to buy one. Droid just came out which has tweeting capability. This device is really for a non-connected, non-mobile user. Perhaps my grandmother would like one for Christmas? But then how do you explain the whole twitter thing? And then explain why she needs to be connected 24/7 to it??
