Palm just released Palm Centro, the smallest smart phone yet where they’ve managed to fit a lot in a small package. If you look the handset closer, you will easily find that the Palm Centro is a smaller, more modern looking Treo with many of the same features, including a QWERTY keypad with tiny keys. The design seems targeted at a younger, less business oriented group of users attracted to sleek smart phones such as the BlackBerry Pearl or iPhone.
