I'm glad I stumbled on this thread as I was going to buy the unlimited version today. This may be a stupid question but does this go for laptops also? I have to travel from time to time for work and use the laptop when on the road and away from the PC. My home PC and my Laptop are configured exactly the same (Same operating sys., software, and security software the only differance is the wallpaper so when I have them on the kvm doing updates and sync. doc's I can tell them apart) and only one is in use at a time by me. My other software including M$'s office pro. 2003 allows this as long as it is used by one user on both. As to paying $160.00 for two unlimited licences just to use one on a laptop that is used Infrequently is a little much.
