My Last ThinkPad, a T30, I dropped a couple of times while it was running. Even broke off a corner on the front outer shell. Didn't miss a beat, and kept on running both times. The only issue I ever had with it, was more my fault. I kept the thing running so much, and I have fury critters, that the CPU fan got clogged up and began giving fan errors, running slow and making noise. Download of the service manual; disassembly is remarkably straight forward; removal of the heat sink fan, cleaning and re-assembly took care of the problem. Anyway, the mouse is a reason I won't buy a MacBook, or any other laptop that doesn't utilize a trackpoint.
I do love my pocket Mac (iPhone) though.
My T400s replaced a 2 year old R61 that ran and ran like a tank. The thing never gave me a moment’s problems. I have Vista Business 64 bit on the T400s, and will soon upgrade it to Windows 7 Professional. I’m installing OpenSolaris on the R61 and I’ll keep it as a backup/test machine. As great as the R61 is, the T400s is 10x better.
