They make a phone that runs an interface that looks like shit
Odd observation. My partner has a Windows phone and the UI is the only thing about it that I actually like. It's clean and easy to use (I use Android on my phone and iOS on my tablet, so I have a solid basis for comparison here) and so far the only mobile UI that hasn't managed to piss me off. On the other hand, the fact that she needs to test her alarm before going to sleep because sometimes the phone needs a reboot to allow alarms to make a noise and that there's practically nothing in the App Store that you'd want are real problems for adoption.
