a. Buy Mac OS X Lion
b. Either setup some kind of VM for it or dual boot it(Hackintosh maybe?)
c. I know that OS X is very picky on its specs, if I have better specs that a MBP would it still work with my computer no problem? I don't feel like having to deal with anything complex as I will be eager to get on and learn about my new OS.
Just a little note:
The accessories are mostly just a carrying case and a cooling station/mat.
This comes with a 128GB SSD, i7 2630QM, 8GB RAM, and has a decent 2GB NVIDIA(I will be playing some games on this and I know that as a base it gets 36 FPS on StarCraft II on Ultra graphics), oh and it is only $1400 .
