Smartphones/Crackberrys

I have a Samsung SCH-i730 (Verizon), which I don't think they still offer. I selected it because it has MS Pocket PC 2003 OS, I was having problems with WM5 devices. Between being more stable than WM, and having MS Terminal Services client - which comes in very handy for my job - it was better for me. I haven't done any research on WM6, so it may be better now.
