the main reason i use N900 is for
1.its qwerty
2.IM &VOIP integration(BEST IN CLASS)
3.Browser(though its old its Gold)
4.Software support from a wonderful forum.. i bet no other phone will get a straight 4th year support
5.and last but not the least MAEMO..(keeps everything simple)

after 3yrs with my N900 i still couldn't figure out whether this is a smartphone/tablet/fablet

Best in class!!!

long live the community.. Long live N900..
