Windows Phone OS (whatever it's called this week) just had so many bad details, it was like walking around and constantly tripping on things.
One example: I wanted to run with a white background instead of black. When doing that, the white-on-transparent icons disappeared.

Things like that might have been fixed in 8.1, but 8.0 was the third major release of this UI (after 7.0 and 7.5) and they should have caught a lot of things like that by then.
There are a lot of places where an overuse of transparency and other effects causes more harm than good. In trying to make something that looks better than iOS, they went a little too far with the effects.
Here's another place where white text on top of random backgrounds -- which happen to contain white -- falls apart. (The one on the left looks OK on a big monitor but they were pretty bad on the phone. And you can see how if the photos had more white in the wrong place, it would be even worse.)

For what it's worth, I think iOS 7 was a big step back from iOS 6 in a lot of ways too -- too many thin lines; not enough contrast.
What you said was exactly my idea -- for $59, it was WAY better hardware and software (from a stability point of view, at least) than some generic Android-based media player, but every single task I tried to do had some obstacles. And it wasn't just a case of being used to iOS -- I use Mac OS and Windows every day at work -- it was that everything MS did differently, they did worse. I just returned it after a few weeks. If someone gave me one for free, I still wouldn't use it.
