Flawless performance. This is one monster of a laptop, the best I've ever used. The 17" 1080p display (1920x1080) is just about the best screen you can desire on a laptop. Perfect combination of large size and high resolution (a friend of mine has a Surface Pro and 1920x1080 on a 10" screen is simply ridiculous. You'd need a magnifier to see anything!)
Even tried hooking it up to my studio's RME UFX via Firewire and it works perfectly (which means it's OK to use with FW interfaces, unlike many other PC laptops.)
