What do you think of the thinkpad t510?
A "flat" question also generates a corresponding answer:
"Sufficient for my purpose".
As good as the device was, the T510 is too thin these days. Had such a thing at work 3 years ago (boss and IT were just too stingy and new equipment to buy) and that was no fun to work with. It would be better to save a few euro and get a current device or to look for more up-to-date refurbished devices (mostly leasing returns from companies that were checked if everything is ok).
