The good people at Treo Central posted a review of a flip lid case for the Treo 650 called the i-Volution T66. I usually agree with what I read at Treo Central, but they actually loved this thing. Basically, the case takes the sleekest, most accessible and advanced smart phone in the history of man, and buries it, resulting in a bloated, unwieldy, heavier, noxious-looking flip-phone from the 80s. You have to remove the Treo from this thing to take pictures and synchronize. Dozens of the most brilliant engineering minds in Silicon Valley toiled night and day for two years to squeeze all those features into a relatively thin device. The i-Volution doubles the thickness in an instant. (Of course, I'll probably drop and smash my Treo at some point, and wish I had one of these things...)
