i'm still gushing a little bit about this thinkpad just for how amazed i am at how capable a 10 year laptop can still be??? i can see why people like old thinkpads so much too, this thing feels pretty solid
@Morgan i imagine the hinge on a x61t will be a bit more problematic :s
@squirrel Hrm... good point. Forgot it was a swivelything. D:
@squirrel Ikr? I'm amazed by their repairability/replaceability too.
Keyboard breaks, or needs cleaning? Just a few screws and it's out.
RAM upgrade? Just one screw, maybe two at most.
Hinges need tightening/replacing? ...you get the idea.
