HI, I'm still waiting for my MBA 2012. Its been shipped and probably will get it in two days. This is my first macbook and I really have little knowledge about macbook. These are my questions. 1. Do I need to calibrate my MBA once I get it? 2. Do games such as Diablo 3, WOW etc run on MAC OS X or Windows(bootcamp/parallels). 3. What are the things that I should do once I get my macs(important things)? Cheers -edited questions- 4. about external hdd, i have the normal one, can it operate on MAC. my friend said something about partitioning, so quite not sure about it. So I can use the normal external HDD without buying the specialize for Mac?
