My friend Nathan Lee was contemplating the MacBook Pro vs. MacBook Air decision that so many of us are facing. He came up with a handy equation that solves the issue perfectly. I'm proud to introduce the world to the Lee Equation:
Z = D - L
D is the number of days in a month your MacBook would be on a desk.
L is the number of days in a month your MacBook will be on your lap.
If Z is a positive number, get the Pro
If Z is a negative number, get the Air.
