Not only that, it's hard to find a decent high-performance laptop that has a decent screen. If I were to upgrade now I might think of going with the Lenovo T430u, except it has a 720p 16:9 TN screen. How long until it's possible to buy an ultrabook with a 1080p or higher resolution IPS display? And hoping for a 16:10 aspect ratio is probably out of the question.
Those are getting there ... but the GPUs are all weak.
The closest I have seen to what I want is the ASUS u500vz which has a decent mobile GPU, but it's extremely hard to get hold of (at least in my country).
