Just got my 27 and the screen is brilliant. No yellow, no bleed (if there is, then I can't see it) but the on off button is stiff and makes a really strong click. My 2008s on off button is much smoother and barely makes a sound. Kind of like the home button on an iphone. Just wondering if this is normal? How are others buttons? It's not a big deal, just wondering. I'm definitely happy with the screen and no way I want to change it. It also looks brilliant. Much better than in pictures. Ace!
