Got mine in january 2010 as part of the nokia/nielson usage trial bonus i got to keep it when the usage trial was up. My version is 2101. can overclock safely to 1150, no problems with keyboard or usb (filed teeth off charger and data leads, very careful with it) never been dropped but one scratch to bevel from wedding ring whilst in pocket. No dead pixels
