At my company, those of us who work remotely use our laptop to Remote Console into one more Virtual PCs or just a desktop tucked away in a forlorn cubicle. In the case of a Virtual PC, the images get routinely backed up by server admins, so we don't even need to worry about it. There is no confidential or valuable data stored on the laptop hardware, so if it gets lost or stolen the cost of replacement is $350; that's how much I paid for the laptop I'm using now. In a pinch, I could even borrow my wife's laptop and miss nothing.
