Hi Guys I ordered Yesterday my first Mac ever. A MacBook Pro 15 2011. I hope she will arrive with Lion pre-installed. BTW I Ordered too a 750GB Scorpio Black and a Maccally FW800 case to swap the base 500GB hdd. Later as I consider I'll upgrade ram to 8GB. Most work I plan to do is 3D CAD, some Xcode programming (OSX & iOS). I hope you cold give me a receip for just Convert, on What to do and What Dont. Regards to Every One here. I'm from Venezuela, A Country Soon to be Free Again.
