get a mac book pro... if you have a local apple store, they will probably have a student discount which when you buy a mac book pro they give you a free printer and itouch, thats what i did before my freshmen year.
Apple store offers students like 100 dollar discount and does NOT have an ADH warranty plan. Go though Best Buy. Especially if you're like me and get a free replacement every 12 or so months (lol, I'm cursed...)
I'm a screenwriting major and needed a Mac for Final Cut, an editing program. So when my Sony pooped on me, I investigated.
Mind I know next to nothing of computers and hardware but from personal experience.... HP sucks, Asus is worse, Gateway is ok, Toshiba is a good computer for cheap. My Vaio was my favorite PC that I had. It was the hardiest and all-around best PC I have played with/owned.
That being said, I also love my Apple. I've got a MacBook Pro. Stock, it can handle Final Cut Pro X (Not a small program) with little problems. I did have to get the upgraded OS though. But now I can search the web, run FCP, and bounce around in word documents. If you do get an Apple, don't get their office thing. I don't like it. Pay the extra money to just get regular Office. And another thing about the Apple, its hardy. I've dropped my laptop so many times! Its downright disgraceful but also the reason I didn't go through Apple to get the thing in the first place. I've got two dents and some modest scratches on the outside of the machine but it does not seem to have affected the overall performance at all.
Well, that was probably next to useless, but its the best I got...Good luck!
