It's been almost 2 years since the Treo 700wx came out on Sprint, and now we have its thoroughly modern replacement: the Treo 800w. This is the first Treo to sport the big four: GPS WiFi, EVDO Rev. A and Bluetooth. Looking like an old school Treo mixed with a dash of Centro, the 5 ounce 800w has come down in size while maintaining that excellent Palm keyboard. This Windows Mobile 6.1 Professional phone has a 320 x 320 display, a 2 megapixel camera, microSD card slot and a 333MHz processor with plenty of memory behind it.
