@joeyh Mine definitely has a fan, but it's a fairly quite one. I like the screen on mine (brigh, manylots pixels), though I need to fix grub and kernel to use a bigger font (desktop sw is ok). 13" screen.
I do not like the keyboard, however. I make a lot more typos than with my ext one. Record so far, on the Yoga, is 15 types mistyping password in a row.
