ThinkPads are quite reliable, in my experience. We haven't sold many from our small shop, about 25 in six years. Only one has had an issue, and that was due to the customer using in on the ocean in his boat. The copper was oxidized. Still, the only thing that didn't work was the touch pad. The track point still worked, so it was usable. My wife and I use ThinkPads. We find them to be quite reliable. Linux Mint works well on them also.
