That's my current laptop since 2+ years go and I love it. Battery lasts a day no prob for regular work. If you're constantly compiling it won't, but then on battery it throttles a lot so it gives you good balance.

Anyway, with tlp you can tweak it a lot, I'm mostly going with the defaults, just lowered the max charge to protect the battery.

Only thing not working out of the box on Ubuntu is the fingerprint reader. I read that there are ways but I haven't bothered.

In the end, once you reach critical mass of quality comments, you don't need the huge numbers of trash filler you find on reddit.

I second Antichamber, cool mechanics and ambient and on the shortish side. I had it gifted by a friend that knows I like the kind of games you're looking for.
