I agree. N900 was one of the best phones experiences, and a pretty good mobile computing experience. Then mine succumbed to the lens-cap-sensor-preventing-sd-card-from-being-recognized bug. Which quickly made it a whole lot less useful.
i personally found mine an outstanding mobile computing experience, but as a phone it was pretty mediocre. the ergonomics of holding it to your ear weren't all that great, and they never did fix the bug where it took so long to swap the phone app in that the caller hung up.
what finally made me give up on it and move to android, though, was the (also never fixed) bug where the gps would take anywhere from 20 minutes to forever to get a lock.
that said, i am very tempted to move back to meego if this effort takes off and has decent hardware. i loved how easy and pleasant it was to write little personal apps for the n900.
the promise of meego was one original reasons I picked up the N900. Between Jolla continuing w/ Meego, FirefoxOS, and a newly open WebOS - I'm quite bullish on the future of handsets.
