We have fleet of about 75 Thinkpads, and with few exceptions, they just keep going. About a third of them are 4 (or more) years old. They are not used lightly, either - they are "desktop replacements" for the users. We've replaced a couple dozen keyboards over the years - the letters are just painted on, not an inlay, and do wear off.

Well, OK, there was the time the employee showed up at the gate with one too many carry-ons, and checked the briefcase with the laptop... Idiot. She got a replacement desktop.

I just hope Lenovo keeps the standards up.
