I am starting college on the 28th and i need to get a laptop. I am in a 3-2 program for physics and either mechanical or electrical engineering so i wouldn't be starting to use any graphics intensive modeling programs until my fourth year. My question is two fold. First off, should I get a MB pro 13inch now and expect to get a pc for engineering when the time comes? Or should I just stick with a mac and get parallels when the time comes? Secondly, if I go with the mac for all 5 years should i go with the $1199 ($1049 with my student discount) 13 inch MB pro or the $1799 ($1649 w/ student discount) 15 inch MB pro? Oh and should I go for the AppleCare 3yr warranty or a third party warranty provider like Safeware that covers accidental damage? Sorry for the 20Q guys but I appreciate any advice you can give.
