Hi, I'm going to be going to a uni in NJ pretty soon and I'm going to be to be a freshman majoring in mechanical engineering. I don't know what kind of programs I will have to run. When I took a tour of the school, I noticed how small the writing surface was in the lecture halls and I'm a bit worried that the 15" will simply be too large. I did go to the labs and they had Dell workstations with all the needed programs, but I would rather study in my dorm, my roommate is also an engineer! Would a 13" have enough to get me through 4 years of school? Is it worth sacrificing performance for portability? I don't know what I will be required to run on my MBP, maybe even Boot Camp? Somethings that might help making the decisions are that I am Single Male Heterosexual Caucasian 5'10" - 172lbs Mechanical Engineer Male roommate Catholic Cats back at home I'm taking 5 courses (carrying the MBP) Will be walking from class to class, no bike or scooter. Thanks, any advice will be appreciated, especially from any engineers here. I must make my purchase before August 24th. EDIT: Half of you have told me to get a 13" because I will not have many of the programs on my own computer and the other half tell me that the power from the 15" will be useful, especially if I plan on using it for 4 years. One person commented that I could just get the 13" MBA instead of a 13" MBP, because the MBA beats the 13" MBP in benchmarks, even if that is true, please remember that I am a heterosexual male. I can't buy a MBA! Another commenter suggested that I get a 17" if I wanted to be a real man, but I think that's a bit too much for me, I'm not trying to be Chuck Norris or Rambo guys. The anti-glare advice does interest me now that I think about it, but I'm afraid that going away from the black normal border will catch a few looks. Should I just get the 15"? Money is not important. What kind of accessories do I need other than a leather case? I'm trying to meet nice Catholic girls as well.
