I think the iPhone has raised the bar, and right now, on its' own, Windows Mobile doesn't come close to what the average user appreciates. TouchFlo 3D is a good buffer between the user and the OS, but those stylus-hungry screens are never far away.
I don't have an iPhone, I have a HTC Touch Cruise. I've been able to spend some time with other peoples iPhones though and if it weren't for the pricey voice, data, and messaging options, my number would already be ported.
I've been using MS devices since the first monochrome clamshells from HP. It's been a fun hobby, getting 1 or 2 devices a year, etc. At this point though, I'd gladly trade it all in for the sleek, elegant iPhone that just plain works. People that have them really seem to love them -- the first person that let me take a look actually asked me if my hands were clean before they would hand it over
