Pictures of Sprint's olive green Palm Centro surface
Ryan at PalmInfoCenter has noted some different details about this batch of Palm Centro's, such as the darker gray trim around the navigational buttons and sides, a soft touch finish (thus removing the problem of fingerprints, for the most part), and a "more grippy keyboard." He also notes that the Centro line is now available in seven colors. Click through for more images of the device.
