I've had a Thinkpad X1 Extreme for a year. I love a lot about this machine, but I had to send it back for repairs (essentially replacement) twice. The first time, the keyboard was flaking out; the GHB keys around the mouse nub were repeating and/or not registering, then the machine started crashing/rebooting randomly, and finally it crashed during a BIOS upgrade and bricked itself. They replaced basically the entire machine (possibly re-used the display), and it seemed fine, until I tried to run a game on it. Then I realized that the Nvidia graphics weren't working at all; only the Intel HD graphics worked. This was a hardware issue, not simply a driver problem. They replaced the entire motherboard again. Both times I lost a full two days installing and configuring the replacement system.

It's working great now, for the moment, and I still haven't seen a better laptop option, but I'm going to be hesitant to buy any more Lenovo products. Between wrestling with the broken machines and then waiting on repairs, I lost months of usability. Now my warranty is expired, I wasn't able to extend it (their warranty extension policy seems intentionally designed to prevent you extending), and if it bricks again, I've got a $2800 (original price) doorstop.

When it works, it's the best laptop I've ever owned. Here's hoping I get at least another year out of it.

This seems to be how many people feel about Lenovo now. Great if it works, but seems to need multiple replacements before getting a properly working system.

I just got the Extreme 2, and immediately ran into the keyboard issue. The matte screen has some light bleeding in the corner too.

It's a bit aggravating that laptops with a high price point can have bad design or quality control issues.
