So I will be headed off to college in about a month and I still need to purchase a laptop. I have been doing some research the past few weeks but still the question is mac or pc? My main concern is due to the programs I will be running in college (AutoCAD for example) that are fairly intensive programs. I would love to get a mac because I feel they can be more dependable over the long run (5 years...I would rather not buy another laptop midway through college). So mainly my question is asking, even though most of the students entering engineering us pc's, could I still be able to get a MBP and have a computer that works just as well as a PC? Right now, if I were to get a mac, I am looking at the 13" 2.3 GHz intel core i5 macbook pro. And I would like to install parallels 6 on it to run either windows xp pro or windows 7 (the two OS's my university can give me). I am not concerned about bootcamp because I dont want to hassel with rebooting the computer to switch. Also, another question, would I be better off to upgrade to the 8gb RAM if I am running parallels and using that to run my engineering programs? I am afread that if I only stick with the 4gb RAM the 3D programs will not run well. Other notes: I will be installing Microsoft office 07 home and student for windows. I do not care so much that macs are more expensive than PC's, I just need some suggestions on how powerful the mac needs to be if I decide to go that route or some good reasons to stick with strictly PC again. Thanks a ton!
