I've used them all and I still prefer the N900. Even though it can't record/playback 720p videos and only having a now-smallish 3.5" LCD, I still LOVE my N900 over ANY other phone even to this day. (I bought it on pre-order back in 2009) Have ran it constantly at 1Ghz for over a year now. Zero issues. I just wish it had more RAM....
