... and its already in the shop!!!! No yellowing issues thankfully but dirt under the screen and a faulty superdrive that only works when the screen isn't tilted!!!! Massive PITA getting a 27" to the store, Apple helpful as ever though! Its my first time using the Genius Bar, apparently they need access to my admin account - is this normal? I was a bit reluctant as I have work stuff on it not to mention some glorious HD porn but the admin account was needed to run tests that could not be done under a guest account? I'm stuck with my 13" MacBook for a week How can there be so many problems with the 27s???
