If you are a big picture kind of picture, looking for what is beyond the Treo 800w, then the Treo 850w is the answer you have been seeking. The device was revealed this morning in some spy shots, and it looks surprisingly similar to the Centro. The device differs quite a but even from the still un released Treo 800w, such a departure in models you would assume to be very similar is unusual, especially considering how the Treo line has remained virtually unchanged over the years.

The device very obviously borrows heavily from the Centro. If I did not know it was a member of the Treo line thanks to that logo, I would have assumed it was a new version of the Centro. Like the Centro, the design has changed a lot. Also like the Centro, the keys are very small. Also, the controls at the top are Centro esque, but the buttons on the side which I assume are send and end buttons, are unique to this device.

Unlike the Centro, this thing is powered by Windows Mobile. Also, appears as if it is running the new version of Internet Explorer Mobile that we have heard so much about. Little is known about the device, but we do know it has a 400MHz processor, and 100MB of RAM. That should be plenty of power for the device to work with. It looks good, and if future Treo devices will look like this, many people may be taking a second look at Palm.
