I'm thinking about getting a MBP (have one at work) because the hardware is shiny and OSX is useful/needed for some things (iOS development, Unity development). However I'd much rather run Linux as the base OS. That setup wouldn't violate the EULA. I guess I'll spin up a VB-image on this OSX-MBP and see how it goes :) Useful.
You're going to miss out on firmware updates and have bad battery life.
