First off since you have a problem with the smaller screen, how big of a screen do you want?
Secondly, if you want one like say a 15" screen or so, then check out Sony FS series if you really want a Sony screen, or you can listen to every other person on these forums and buy an Asus Z71V from any one of the online retailers.
Since you won't be playing games I really don't think that you need it. I would go with something like an Asus W3V (depending on your budget) or if you like something more portable then check out the Gateway M250 model. Its a 14" widescreen, with the new Sonoma platform, 80 gig hd, 1.86 ghz processor, dvd burner, good battery life, and all for about $1400 with a 3-year plan. Since you're going to college just like me I think its necessary to get a good service plan because no matter what computer you get something will happen to it, that's why its good to go through a real company instead of an online merchant. I know that I will get flamed when someone reads this because they bought their Asus online and they love it, blah, blah, blah, but that's just the way that I am and I feel much better having a plan through Gateway then through www.computersales.com
Either way, don't buy an Alienware, it's just a waste of money since you don't game. The Sentia has old hardware and a big price tag and that's just a bad combination.
