i think mine is coming up to 5 or something. i bought it second hand four years ago and took me 3 months to discover that the old owner had removed the Bluetooth Chip. its in alright condition for a veteran, if you take into account everything its been through. i have replaced its fan 2 times and cracked it open countless more to fix other bits. and im on the search for a replacement. but still 'Harold' has served me well
