With regards to the tablet market, I think Android is quite far behind Apple in regards to the quality of the catalog. Take Flipboard for example.
Im sure there are issues. However, thanks to tablet fragmentation I also have a tablet that can do some stuff way better than an ipad or nexus can do. I got the note tablet and the stylus rocks! Neither the nexus or ipad can give me what I (personally need) from a tablet. Im thankful for the more choices fragmentation brings. So yeah, another example of fragmentation is that I have specialized stylus software for my note that my ipad and galaxy tab do not have. Hooray for fragmentation!
