I do as of a couple a weeks ago. Benefits as far as I can tell: mental compartmentalization (this is big; I wish I could write this in 24-pt red Impact font), makes writing off the laptop simple rather than having to estimate personal vs. business use. Downsides: Travelling with two laptops is going to be annoying, expensive if you're paying for the laptops out of pocket. This situation was kind of an accident for me, but I like it, enough that I might go to the trouble of maintaining it.
