If you like Palm OS better, go with the Centro.

The differences with the "squat white phone" (HTC Touch) and the Centro would be:

The HTC Touch has a larger screen, however the Centro's is higher resolution. (320 x 320 vs the HTC's 240 x 320)

The HTC Touch has a slightly better camera

The Centro has a physical QWERTY keyboard, which is actually quite good for its size, as opposed to an onscreen keyboard with the Touch.

The Touch has Wi-Fi so you can still go online when in a Wi-Fi hotspot without a data plan.
