I had 3 different Thinkpads...
The first went down after 1 year with a headcrash. 1. HDD headcrash in my life.
The second one was delivered with bad RAM. Support denied help because of wrong FRU Number. The whole thing went back to the dealer.
The third one died in a loud bang of the power supply and died with it.
About design:
Placing the Ctrl key not on the outside drove me crazy.
The trackcap was horribly to use - an example of bad design par excellence.
The touchpad was bad in all 3 laptops.
