I have a first gen Lenovo X1 Yoga, and it is hands down the best machine, I ever owned. If you don't need the touchscreen/stylus (which both work flawlessy under my Arch linux btw), the X1 Carbon is the same machine sans touch/stylus. So I would always go for an X1. Btw. remember to upgrade the on-site warranty to 5 years from start!
