I switched from Android to the Windows Phone and greatly preferred it. I liked the look, the responsiveness, and the dearth of apps wasn't a problem initially. I was never a huge fan of live tiles, though, because I like my UI to stay still and let me focus on what I focus on. But what ultimately drove me away was the inexplicably shitty Kindle app. I read a lot on my phone, and the Kindle app would skip lines on page turns, for a very disorienting and frustrating reading experience.
