Fragmentation is just Apple's attempt to generate Android FUD. I've owned Android phones since the G1 was release in 2008. I've rarely run into incompatibility issues due to OS or hardware. Doesn't mean it won't happen. Just means it isn't as big a deal as Apple likes to see made out of it. Sure, if you break down the distribution by manufacturer, then Apple appears to be leading the world. Of course, someone should ask Gil Amelio how that analysis worked for Apple back in the 90's.
