I got my air a couple of weeks ago and on day 3 noticed that there were two indents near the bottom of the trackpad. it looks like someone took pliers and squeezed the body to cause these indented circles. It's hard to see with a camera but you can see and touch it and it's clear it's symmetrical. I wasn't worried but it was clearly a factory issue so I took it to apple and they had me mail it in for a refurb replacement. I could have mailed it back to the store for a new model but didn't have the time to worry about that since I travel a lot. Got a brand new machine in 3 days (refurb though) and it's working great. Has anyone has these indents near their trackpad by the clicker on both sides?
