One desktop and one laptop ( portable device ) for one user. At least that's
the way my Office 2007 Pro reads.
Different opinions on what these 2 devices are. Could be 2 laptops, but the
intent is that the licence is for one user, although if you were using the
laptop and your spouse was using the other install, it's not likely
Microsoft or the police would be breaking down your door. I hope ;-)
Office Home and Student 2007 allows install on 3 computers.
