Hey guys, Just picked up a Rev B MBA yesterday new (not the SSD model) and I'm hearing a slight clicking sound coming from the right side of the keyboard every 10 seconds or so. Just made an appointment with the Genius Bar at my local retail store for tomorrow, and I will update the software tonight when I'm back at home. In the meantime, any thoughts? The sound is not loud but extremely annoying. Loving the computer but if they don't give me a new model tomorrow or attempt to fix this issue I'll be forced to return this one (which I bought new at BB for a great price).
