I hardly see how Windows Mobile is a "problem." I have an HTC S743 and it runs just fine. I would have bought an Andriod phone but there are none with AT&T 3G. (UMTS 850/1900.) -- PRescott7-2097
WinMo tends to run slowly on any given piece of hardware, which with a lighter operating system would run like a dream. I'm not bashing WinMo for the heck of it; that's what my last two main phones have run (HTC Touch Pro, HTC Mogul) but neither phone has been a particular speed demon. That said, the Touch Pro is generally quite responsive (thanks HTC for customizing the thing).
