Again, it's all about your priorities. Slick, portable, non-bulky, great gaming laptop - without placing a definite value or range on each of these criteria, this could describe every system we've discussed. If you're going to school on a football scholarship, 20 lbs or less could be your definition of an ultra-light. To me a 17" laptop is an awkward size, regardless of thickness or weight - unless you don't plan to carry it around, in which case why are you bothering looking at anything smaller?
Do you want performance, regardless of size, weight, heat, noise, cost?
Do you want portability, regardless of performance?
Do you want value, regardless of performance, portability?
I can go on, and on...and on.
Bottom line is, if you want the best all-around PC, go back to your first choice. If you want a laptop that is the best in a certain category, be prepared to make sacrifices in some or all of it's other aspects.
