I think the OP is looking for something in the 14in or smaller range, the linked model is a 16in notebook and not really in the ultrabook category. Looks nice though.
The sony s I linked is the biggest I'm willing to go to. And thats only because it does not weigh any more then my current m11x.
I only game on it once in a blue moon. But daily I use my laptop for watching work out videos. And its getting very old to have to adjust the screen every time the work out changes.
As for weight, while I dont travel often for work/vacation. I do make a few plane trips + road trips each year. And if I do travel for work, where I go, rarely do I travel direct. 2 flights is a good trip. 3 standard. And 4 connections happen as well. So I quickly learned, that a large/heavy laptop just plane sucks. esspically if you are fitting everything into carry ons.
So far I've narrowed it down to the the sony s (a bit to large, but weight wise is good) and the zenbook prime, but I might skip the gaming part of it because to me, its not worth paying 300+ dollars to get the 620m video card, I know it doubles gaming speed. but its just too much of a preimum.
There were alot of good ideas in this thread. Some just didn't pan out after I started digging into them.
The sony s13 still has typical tn display issues. The mac's, well resolution wise they have fallen behind.
