That's because it's a Thinkpad. The T-series had been the Red Hat company issue laptop for years, and has had boatloads of internal support as a result.

You're right in that a Thinkpad will mostly work out of the box long as you don't want that Nvidia GPU to work, but everyone else? Good luck. My XPS 15 was a lost cause, losing three quarters of it's battery life under Linux and with countless video problems.

And on a desktop? Hah! Roll the dice baby, and keep rolling them with every update, because sooner or later something's going to break. It always does.
