Hi all, I am looking to purchase my 1st Macbook and I need some advice on what level to get. I would like to be able to run Autocad and Autodesk inventor in either bootcamp or one of the virtual windows programs, also do some basic photo editing and watch the occasional HD video. Where do I start? In a perfect world I would like a 15" screen but if the smaller 13" Macbook Pro's will do what I need then I could save some money and go that way. What do you think?
