Let me list the ones I've had..
701c, 380, 600, 600x, t20, t21, t22, t23, a31p, t40, t41p, (2) t42p's, and soon to have a t43.. hopefully a 'p'.
Don't ask why I've had so many... it's a work related thing, I get a new one more often than I like actually.
The only one to ever let me down was the t20 with a hard drive that developed a problem with it's boot sectors. I was able to recover most of my data however.
I travel weekly all over the world, but mostly within N. America, and through numerous drops, scrapes, and all kinds of other situations, my thinkpads have never let me down as much as some others brands we've had on our team, or that I've personally carried.
