why fightting here, no one can compare these two, its about windows and linux. windows has nice GUI interface where people can reach every option by pointing, on linux side most of them free and far more staible. most people like n900 coz of its capability to put normall linux tools, that there using already on desktops so as a linux phone this is the best phone in the market that we can play with. In other hand some people dont want play with the commands, they goes for phone's beauty and the other extra feture such as cam, screen, gui interface so there is no point of fighting over 2 operating systems. all depends on the users interest, for me n900 is best phone i ever had and thats the only phone on market for my requirement.
sorry for my bad english
