loll, that's what most people in that forum are saying, it's up to your own impressions :P
I say it could be the camera. The N8 has an incredibly amazing camera for a mobile device, and I'm 100% there is no logic in adding the same camera module on the N9 (for business reasons). I just hope we don't get the same 5mp lens that we got from N900...which itself got from the N97.
