I do not own a 700p(YET), but I've had the 650 since it came out & I've also had a windows mobile phone, so I feel qualified to advise you. I would definitely take the 700p. Why? Palm os is faster than WM even with a slower processor, it is more versatile, more stable, less bloated, and there are like INFINITY more apps for Palm OS, many of them free. Windows mobile has the familiarity of windows, but also all the problems. It locks up, is achingly slow(I would actually count to 3 or 4 before the start menu would drop down on the phone I had), crashes constantly, and has all sorts of odd glitches. In the 3 weeks that I had my WM phone, I had to hard reset like 4 or 5 times b/c of mysterious glitches. You would be missing out on a friggin' great phone if you get the Q.
