Hello,
I have a laptop that I purchased online at Dell.com. Mainly it was for when I go to school but, I'm graduated now. Since graduation it has been collecting dust, haha. I always custom build my desktops but, if I where to purchase a desktop or laptop the 3 things I would really look at is the:
1. Memory / RAM - I would want something with a kick (3GB0.
2. CPU - I want something that will move (Quad).
3. Harddrive - I need something large enough where space is not an issue (500GB).
For laptops size / weight is an issue. Thats just something I would have to compare given the specs of the laptop.
