I also have an X13s and it's also the best laptop I've owned... Sort of.

I ran Windows on it up until a few months ago and it was as you said, delightful. Long battery life, fanless, great size, great screen. I put Ubuntu on it (where they've mainlined a good bit of things), and it's still just not very good. Sleep doesn't work (and never will without Qualcomm), certain things still just crash on occasion -- but I do think the webcam works.

I'll likely put Windows back on at some point, which is a shame, because the laptop is great, but Windows is terrible. I simply do not believe any claims Qualcomm has about future support, as much as I'd love to see a newer Thinkpad device with full ARM support.
