Looks indeed interesting. But compared to e.g. MacBook Air it can get very loud :)

and also 2560 × 1600 retina display vs 1920 x 1200 pixel 170 PPI - I don't see myself going back...

It is also available with OLED display, 2880 x 1800 pixel 255 PPI.

Compared to a Macbook Air it can also run x86 OSes, Docker and 32-bit software. There's really no comparison :)
