I also susggest not going with the 650 - old technology and probably the worst Treo put out by Palm. The 650 is plagued with memory problems and resets more than its share of times.

The 800W - I had 3 before giving up on it. The key pad each time went bad. From there I went with a Touch Pro.

The Treo Pro - from my reading, a much better device than the 800W and evidently not plagued with the quality control issues that hit the 800W. The available memory is not as high as it is with the Touch Pro, but I have not read of anyone complaining about it.

The Pre - no real SDK support at this point.

iPhone - do you need multitasking?
