I have Android on a tablet that I use at school. I use Google Docs on there, but since it's a rooted version of Android, I've also set up a chroot directory with Gentoo. I don't have a lot of stuff on it, but I can use Vim and a C compiler to get by without a full on desktop.

My main computer at home is an iMac 2013 (dual booting OS X and Archlinux). I use Arch for most of my day to day work, and only have OS X for compatibility with a few apps that don't have Linux versions.
