The machine is a stunner. I got the most basic model, and it screams through everything I lay on it.
It is very quiet, and the screen to the edges looks fantastic. I also like that the area below the screen got smaller, I never thought that looked good on the previous models.
The screen also as a very wide viewing angle, and you probably won't use it on full brightness.
The machine is so incredibly well built that I cannot believe I am sitting in front of a 1100 € computer.
I also use it with my 52" TV, and the native TV resolution is perfect for mirroring, though I actually dislike the 16:9 ratio on computers for non-video stuff.
All in all, I think will be one of the best Macs I ever owned (and it's my 13th machine).
