I have been accepted into Mechanical Engineering for the fall of 2011 and I am starting to look into laptops. I have used Windows all my life, except for some iBook G4s at my public school. A few people I know have Macbooks and Macbook Pros and I really do like the design. I expect that I will be running some CAD software, which would have to be done in Windows via BootCamp. I like the portability of the 13" (I would use an external monitor with it at my desk), but I don't like that they are underpowered in comparison to the 15" (dual vs quad core). I have a few questions: 1) Is a Mac a good choice for an engineering student given that there are some programs that are only available for Windows? 2) Would you recommend a 13" (high end model) or 15"? 3) Anything else that I should be aware of? Thank you for your help. edit: Sorry I am new to these forums, I just noticed the Buying Tips section that I should have posted this under. Sorry about that, I suspect this will get moved, but I don't think I am able to do it myself.
