Palm accidentally uploaded a presentation about the Palm Treo 850 -- aka Treo Pro -- to a public Palm Web site, where it was spotted by bloggers and posted just about everywhere. It is probably the best looking Treo ever. But is that really saying all that much?It sure looks nice. You can see pictures of it here and here. Looks to have either a black or gun-metal finish to it, with nice sharp lines and clean buttons. My one issue is that it still looks chubby. Palm Treos, even the latest 800w, are a lot thicker than the competition. Motorola, Samsung, Apple, and even RIM seem to know how to make thinner smartphones.

Other details that can be discerned from the presentation are that it will have a full 3.5 mm headset jack for headphones, Wi-Fi, and, of course, a touch screen, which all Palms have. It looks like it will run the Windows Mobile 6.1 platform and will have a micro-USB jack for transferring data.

When this device will launch is unknown, but it will be with a carrier such as T-Mobile or AT&T, because the first version of it will have GSM/UMTS radios.

This phone is a nice improvement for Palm in the looks department. Since the next generation of Palm's own operating system isn't going to be available for a while, Palm needs to do its best with Windows Mobile phones if it is to remain relevant in the competitive smartphone market.
