I just got back from the Apple store in Reading, UK. I booked an appointment because my brand new air had a single dead pixel smack in the middle of the screen. At first I thought i'd just live with it, but since it's new, i gave the bar a chance. Got there, got served earlier than expected and was sent to a Genius named Cole. Cole, for his part, lived up to the job title fully. Knew all about the machine and, despite it being ordered online, stated he would exchange it right then and there (normally, they go back to the point of sale). 40 minutes later I walk out with a brand new air (he even found me one with the samsung drive in it!). So, any of you living in the southern UK, I highly, HIGHLY recommend the reading store in the oracle.
