Well as a previous WM user with an iPhone... WM has all the features I want (including a few missing on the iPhone) except a good browser. I love safari on the iPhone, and I can live without flash.
Even so the UI of the iPhone is a winner. It's designed to be finger based and all the touchscreen WM devices I've used still liked the stylus. Looking back the "take the stylus out" point was a huge barrier to usability,the next biggest was the "slide out the keyboard" point.
My favourite phone was the Cavalier, not a touch screen device, but easy to use and almost everything I needed.
So to get me excited about a WM device again:
- Don't cut any features
- Make the entire UI finger based at a deep level
- fix PIE
- fix sync so it "just works" (Apple has a way to go on this one)
- keep the stuff that's way better then the iPhone: pocket outlook, office, device support (bluetooth etc)
- Have a solid HAL (or whatever) so you (Microsoft) can upgrade my OS and core apps (Live, Outlook, Office and PIE) without having to go out to all the OEMs
Actually that last one would probably get me really excited. My Cavalier will only get 6.1 if the xda folk get it going. Oh and I realise it's probably too big an ask, but I can dream
