Okay I'm gonna be a senior in high school and I'm shopping for a laptop that I can use this upcoming school year and throughout college. I'm looking at either the XPS 1330 or the Inspiron 15...I've built them myself and would like a little feedback on which you think would be the better buy for me. Here is some info. on the two:

They match up evenly almost all around but the Inspiron is cheaper AND has a gb more memory...but I really like the way the XPS looks...so which one do you think I should go with?
XPS: 8
INSPIRON: 8
