I won't answer... I'll let the Nokia-hosted MeeGo conference about N900 DE explain it for me: Please read line one aloud: "This is and will not be for regular end users." Period. You can read the whole text and see more slides by clicking here.
Even the presenter, near the end of the demo video, notes that the camera still has issues, and overall "it needs work... But is surprisingly overall good." Not exactly a ringing endorsement.
