And what are those "things"? If people are interested in a developer's view of the Android situation, the Penny Arcade Report had a really good article on why one dev is avoiding the platform. It's only describes the beginning of the problems, but it's a very good start.
(If anything, the article sells short how many devices there are out there, each with their own weird quirks and bugs, and how much extra testing and debugging time you have to spend dealing with the mess. It's even harder when you write games for tablets, like we do.)
The comments on the post are very worth reading, as they provide a classic example of how evangelists for a platform can be capable of erecting a Reality-Dispersal-Field, through which not even the hardest facts can penetrate.
