I'm migrating to Linux Mint, 99% of steam games work as well as on windows. Those who don't are mostly multiplayer games that insist to have some shitty kernel anticheat.

I'll still keep windows on dual boot when I need it, though.

At my usual supermarket, you can take a scanner thingy and scan your items as you put them in your cart. Once you're at the lane, you put back the scanner in place, pay for your stuff, and it's done.
