Hey Apple Inc. is so cool, but it costs much, it has student offer....with apple you can install any OS you want, but with other computer( like Dell,Microsoft,etc....) you can't install Apple Mac OS X.....
And the first step in buying a computer is taking a better info of the chip....make sure its upgradable.....
Then for gaming there are separate laptops available.......
This Is My Suggestion:
buy a quad processor, or i7 or atom(hafnium)
RAM, so cool if it is 4GB
graphic card= well it goes better for desktops but there are worthful GC for laptops too
then there are lots.....
make sure you buy a computer on a whole sale store( indeed they sell single pieces)
