I wouldn't worry about screen real estate for publishing on your laptop. If you really need more screen you can get an external monitor (I have a high-density 23" Samsung which I love), or you can go do work in whatever lab your department has.
Get the base model and upgrade the hard drive on your own. After a few years you can stick more RAM in it, and you'll be fine.
Enjoy your computer, but enjoy college even more. =)
Thank ya very much! I'm a worldly-minded person in a provincial community, so to say the least I'm really looking forward to college.
