It probably would of been helpful of me to mention that I really don't like netbooks, lol. They're too awkward for me and the screen resolution is too small for my liking. I appreciate the suggestion, though .
TOSHIBA Satellite L635-S3100 13" NoteBook $480
Pentium P6200 2.13GHz CPU (part of the Core i3/i5 family) 4GB RAM 500GB HDD 13.3" 1366x768 LCD w/ Intel HD Graphics.
A nice upgrade in CPU power there but also slightly less game friendly Intel HD graphics.
Not especially thin - but a nice size for toting around and under five pounds.
