I made the switch
Bought a Lenovo Thinkpad P71 for xmas, running XUbuntu (currently might switch after they fix the bug) and I haven't looked back.
The motivator for me was how horrible Windows 10 is (IMO). I still run Win7 on my gaming box and MacOS on an iMac for other task.
Just for giggles I run a Mint 18 VM on the Thinkpad too (I only web surf through VM's never on the host).
