Om gives the N900 (something I have on order from Amazon) a 6 out of 10. That's barely a passing grade.
Granted he reviewed pre-release software, but what I like about it is the "optimized for the T-Mobile network" on which I currently run an Android based MyTouch3 from T-Mobile. Hopefully, by the time I return from the UK and EU I'll have received mine.
Now if it only had a VoIP client....stay tuned.
