I used to love Lenovo - I had a T40, T60, T420s, T440, and a T460. Each one, in the first year I had them, were awful with Linux, but over time they got better. Under Linux, no Lenovo matched the battery life, screen quality, build quality, or touchpad quality of my MacBook Pro. They were usable, but nowhere near as intuitive to use as my MBP. Example: Sleep, on the Lenovos w/ Linux, is a crapshoot. There seemed to be a 50% chance that any time I pulled the Lenovo out of my bag that it would be dead because it never really slept. I never had this problem with any Mac laptop. Battery life, which is a similar situation, also can't be compared. I remember once having to crawl around on the floor under a table at a client site because my Lenovo was dying mid-presentation. All the clients laughed because they had Macs, and only plugged in at night to charge.

Windows is a non-starter for me, and even now Linux is just not well supported enough for a daily driver laptop. I'll gladly remap caps lock to avoid the certain bug-opening that comes with a Linux laptop.
