This was the feeling I had when I had played with the recent versions of WP. It felt like a fantastic OS, and the hardware ran it brilliantly.

My own personal showstopper isn't a fault with the OS, but with how the phones look. Nokia just seems so far behind in terms of designing an attractive phone.

If Nokia were to release a phone that looked as nice as my Galaxy Nexus, had a large screen, and didn't cost an absolute bomb I'd probably go for WP over Android.
