I think the use of a personal license vs. a computer license is this:
If you use your license on both your laptop and the family desktop, but someone else in the family also uses the desktop, you might make the license a personal license, so that the other person can't use the license on the desktop and block you from using it on the laptop. If that's not a concern, you can just install it as a computer license on both machines.
