I just though I'd post my recent purchasing experience. I had read a lot of the reviews/opinions regarding the Macbook Air and finally bit the bullet. Excited, I took my Air back home to eagerly unbox it. Upon first glance, the computer looked great. When I set it on the table, however, the thing rocked back and forth. It wouldn't have bothered me, but each time it rocked, the screen shook. Upon closer examination, I discovered three hairline scratches on the underside of the case, as though it had been set down roughly. I took that Air back and had a very pleasant experience at the Apple store. The Genius told me that it was unacceptable and replaced it without question. I also opened the box in the store and checked for a wobble. Everything checked out. When I got my second air home, I double-checked for wobble and was happy to see that it still didn't exist. I booted up the computer and was about to click through the setup menus when I realized that the button underneath the trackpad was very loose. In fact, it was often unresponsive and even got caught under the case on one occasion. The entire thing rocked back and forth. Taking a closer look at this one as well, I noticed that the magnetic pull between the screen and the bottom of the computer was almost non-existent. Frustrated, I called the manage to report my situation and reluctantly made the 40 minute trip back to the store. Again, the genius was helpful, but this time he seemed to be skeptical, as though I were purposefully damaging the laptops for some undefined purpose. He even tried to convince me that the button was not that bad before finally admitting that it was an obvious defect. Still, the Genius was courteous and helpful. Before I left the store this time, I did a complete, 100% check of the computer. There was no wobble, it booted up perfectly, and the magnetic latch was strong. I noticed a few of the same hairline scratches on the bottom of the case, but I told myself that I could live with them. I've had the working Air for a day now, and I'm wondering how I ever managed without it. I take it everywhere with me and it has already become an invaluable tool. And here's the kicker... At the time of the original purchase, I took advantage of the Back-to-School promotion and bought my girlfriend an iPod Nano. She finally opened it the other day, and realized that the port on the bottom would not accept the charging/usb cable. I also tried it and it is impossible to go in. I tested the cable on multiple iPods and it works flawlessly, so it must be the iPod. I feel like a fool going back to the Apple Store, but it's necessary. I'm not going to spend $200 and get a faulty product. Though I'm a recent Apple convert, I'm already a little disappointed by the lack of manufacturing quality (though I have had many PC laptops fail me, just not all from the same company...). Here's hoping that I won't have any more problems. Has anyone else had a similar experience with the Air?
