My main laptop runs Windows 7 - nearly all development is done on this, compiles using Visual Studio 2008 and Cygwin.
My netbook runs Windows 7 - I do nearly all my social/recreational stuff on that machine. Also it has VGA out and I've come to rely on Win7s projector detection magic for presentations to just work. It's the only machine I travel with.
My top-of-the-range Alum Macbook runs just OSX, got it for xcode, which is gathering dust because most of my dev work is in VS.net and even after months I still can't get into the swing of using OSX.
Machines synced with the amazing DropBox of course.
In serverland, 1 dedicated server (France) and 1 slice (USA) running Ubuntu 9.04 server, the other vps running RHEL; Mono 2.4.2.

I always have a stack of Putty windows open.
