its only a matter of preference. a guy bought the n900 and was not satisfied with it so he moved to the one of the best smartphone candidates of the year. each OS have advantages of its own, depending how people use it. As I see it those who loved their n900 will troll around against those who turned to the competitor. only a few are geeks that can fully utilized the n900, most people are looking for something that is out of the box functionalities. that is why iOS is so popular. it is very straightforward, android is somewhere between iOS and Maemo5. like the sgsII, out of the box functionalities are great but it can be customized but limited. n900 have great capabilities but not for the average users.

that's my opinion only peace
