Palm Centro looks very similar to the already existing and popular Palm Treo 500 but the new Palm Centro is different.
The Palm Centro is a PalmOS 5.4.9 device and has a large square 320×320 pixel display, and it’s also touchscreen. It weighs approximately same as the Treo 500, which is 120 gram (4.2 oz).

Palm Centro sports a 1.3 megapixel camera, microSD expandable memory, a multimedia player and push email. This device works only on a CDMA2000 / EvDO network, which will not allow this device to work in Europe and rest of the world.
Palm Centro is exclusive to the US Sprint network and will offer a variety of 3G services such as video and audio downloads. Other North American networks will probably carry the Centro later.
The Palm Centro is available in Ruby and Onyx colour scheme, and its dimensions are 4.22 x 2.11 x 0.73 inches (107 x 54 x 18.5mm) and has 3.5 hours talktime with up to 12 days standby time.
