I currently run openSUSE for its relatively up-to-date programs, working wireless drivers (especially for my previous system with a POS Broadcom chip), etc. I now have a system with slightly more Linux-friendly drivers (Intel wireless), I just have to wait for the major distros to support it because it's so new (Debian Testing supposedly does, I just don't want to run Testing...). I might then switch to another distro, but I'm staying with Linux. I primarily use the i3 window manager, except on occasion when I want to play a game on Steam (which doesn't seem to get along too well with i3, so I temporarily switch to KDE).
Ironically, after "upgrading" from the crap that is Windows 8 that the laptop came with to Windows 8.1, the damn operating system can't even boot half the time without locking up. Not that big of a deal, since I rarely need it... but god damn, does it get annoying when I would like to reboot into it for whatever reason. Even worse is when I spend 5 reboots and 15 minutes just to spend 2 or 3 minutes actually doing something in the OS.
