Edit: If you've had to return your first MBA for a replacement, I'd appreciate if you posted and got counted, I'm sure a lot of us would be curious to know! thanks. They were all great machines, I was quite satisfied with all aspects of performance, but it seems like the product is a little rough around the edges. I ended up with a base MBP today. MBA 1: airport card was not detected when waking from sleep, and one of the feet did not touch the table MBA 2: case was malformed, lower shell had some jaggedy gaps (up to 2mm) at the seam, and one of the feet did not touch the table MBA 3: on day 5 the lid started making a clicking noise as though some plastic or glue part had come loose, and the problem was intensified as the laptop warmed up. MBP: perfect so far, kind of boring and familiar since I'm coming from a PB G4. But good times anyway. Anyone else have this kind of luck? It's worth mentioning I've had to go back to replace a lot of defective apple products, including an apple remote, an aluminum keyboard, and an iPhone with an abundance of stuck pixels. I'd be more pissed off if the products weren't so thought-out and well-designed to begin with.
