Speaking personally. I had the same reaction. I realized I could sign in using my GitHub account for MCC, which was… weird. Since it was just their normal web/auth page you could click around and do it in that tiny little webview. -_- Ridiculous, but I wasn’t going to make a new account to play a single player game. I did nearly refund it out of spite, but didn’t.
Oooh. So I keep a Dell Mini 10 (1GB RAM, ~1GHz Atom) around with Haiku on it. It’s brilliant! The UI is super snappy even on such an old machine, and I can even run pretty modern software on it. I used it yesterday to work on my website a bit. :)
