Home: Laptop with Slackware. A lot of the supposedly more user-friendly (okay, less user-hostile) distributions have a knack for leaving a mess of my machine without my telling them to. Or ignoring my configuration files. Or changing their init system every other release. Slackware gives me vi and bash and then stays out of my way, so I have no need to switch. The laptop has a bit of exotic hardware that plays poorly on the BSD flavours; otherwise, I would probably use one of them.

Work: The thing sitting under my desk runs XP. It has three purposes: Outlook, internal IM, and a NoMachine session hooked up to a VM with CentOS 5.
