I spent over $2500 on a ThinkPad X1 Extreme three years ago. Died within three months (wouldn't turn on). Lenovo replaced all the innards, but then the 3D video didn't work at all. Had it replaced again. Two full replacements in the first six months. Later, I spilled a drink on the keyboard, and despite their claims of spill-resistant keyboards, it permanently fried eight random keys. By then it was past the warranty period (one year) and Lenovo was unwilling to service it at all. I was ready to pay, but it's not even an option. They told me I had to go through a third party. Couldn't even get any supposed "authorized repair center" to respond to my requests for estimates. A few months later, the video started going, and now it locks up a few minutes after booting.

I get that shit happens and sometimes products have defects. I'm willing to put up with a reasonable amount of annoyance. I'll never buy another Lenovo product, though, because once you're out of warranty, you may as well throw the thing away. They don't care at all.
