I will be enrolling as a graduate student in about one month, and I've decided to make the switch to . I've done some homework, but as a new buyer making a pretty big investment, I need some guidance from experienced users. I will have an iMac at home as my primary machine, but I need a notebook to take to class and the library daily. So it will be a secondary machine, but it will get a lot of use. I will be purchasing it with a student loan, so anything under approx. $2400 is not prohibitively expensive. I don't want to take out more loans than is reasonable, but my main concern is to get the most suitable machine for my needs. Taking into account the student discount + applecare, prices of the machines I'm considering are: MB: $1182 (base white) through $1582 (BlackBook) MBA: $1882 MBP: $2038 Lightweight is a huge plus because it will be in and out of my backpack a few times every day, but I realize that none of the notebooks are very heavy. 15.4'' is fine, but I prefer the smaller screen size. I dislike the look of the white MacBook. I will need to install Windows (for use on occasional exams only). I will use the machine for word processing/document storage, internet, small music library... not really a power notebook user, but a frequent user. All else being equal, I would actually prefer not to have a built-in optical drive, because I never use one (and I prefer simplicity over extra components). The limited ports of the MBA would not be an inconvenience for me. I wish I could wait for the next refresh of the MB and MBP this summer or fall to see what happens with that, but I can't. I would really appreciate recommendations... thank you!
