Introducing the Peek, a one trick pony that is designed to give you your unlimited email for a low price. The unit costs $99, and service is $20/month. The interface looks to be simple enough, and the color screen presents a readable display.
The ideal of having a device dedicated to email could catch on, if one thing is true – the device does its one function very well. If it does not, and a smartphone is just as adept, then I doubt the Peek will see much of a market share. But just imagine the market if it works well and it is easy to use.
