It's the first Twitter-dedicated device in the world.  Twitter Peek allows you to view Twitter anytime you want.  Send tweets, read tweets, retweet, all on a handheld Blackberry-looking device.  Twitter Peek became available today at a price of $99 with six months of service. After that, service is $7.95.  You can also buy the unit with lifetime service for $199.  It makes sense if you don't use a smartphone and want a small device to tweet with.  Think about it, the data plan on your smart phone may be $360 dollars a year.  Twitter Peek is available on Amazon and at the Twitter Peek site.
