With yesterday's release of the Palm Treo 800w, which runs Microsoft Windows Mobile Professional 6.1, Palm is hoping to capitalize on the ever spreading Apple iPhone 3G fever. The latest version of Palm's signature handset measures 4.4 x 2.3 x 0.7 inches and weighs in at 5 ounces, making it slimmer and more streamlined than earlier Treo iterations. The 800w also features GPS (pictured), Wi-Fi and EVDO Rev. A.
