those sonys are nice looking.
For a student though I'd go with Dell. Built one for my cousin (well configured it

) online for her trip to France. 5 months later still doing great though shes on a vacation from her teaching in France and is touring England now. She'll be back in about 2 months and from what shes said shes really loving the laptop. I enjoyed it too while it was here.
Very responsive, no really cheap pieces, sturdy construction good battery life, which is one of the differences between a cheap laptop and a good laptop.
My grandma got my grandpa a Compaq a few christmas's ago and even new there was one problem after another. The LAN stopped working, the cd-rom was iffy at best after about a year of very periodic use. It gets VERY hot, and its touchpad goes funky everyonce and a while. I see a lot of that from the cheaper laptops. Just components arent quality. The CPU may be a really good CPU but how did they design the heatsink for it? Who made the touchpad? Its those little things that really can kill a laptop experience.
I'd deffinatly suggest a dell though, they are great little student pcs and you can get pretty good discounts as a student also. If not dell, Toshibas are nice too.
