I would guess you'll probably get at best mediocre battery life not running OS X as the host OS.

If you happen to have any issues with hardware (that are actually hardware issues) it will also most likely be a lot harder (i.e. more involved) to get support from an Apple Store.

Also, from reading the quoted text about the "virtualisation" clause in the EULA - it may only be "acceptable" (by Apple's terms) to virtualise OS X on top of OS X (emphasis mine):

> to install, use and run up to two (2) additional copies or instances of the Apple Software within virtual operating system environments on each Mac Computer you own or control that is already running the Apple Software

I also understand, that if you bootcamp to get windows/linux that the thunderbolt ports aren't completely compliant... Ie you'll see issues connecting/disconnecting devices after booting (like the wired ethernet).

Also, there's no way to install firmware updates released by apple unless you're running OS X on the hardware - though you can keep a crappy USB drive around to boot from to accomplish this OK.
