I just felt like sharing my experience! I bought a 2011 13" 256GB MacBook Air two weeks ago. Things were going pretty well, and I got the Samsung display AND the Samsung SSD. But I noticed that my return and shift keys made a small "crunch"-like sound when getting clicked. They were slightly more resistant than the rest of the keys. Also, my computer wasn't built tightly enough, and when using it or applying even the SLIGHTEST bit of pressure on certain parts, the computer made a click noise. I thought it was questionable and annoying, but I figured most of the Airs must have that problem due to being made so thin. Yesterday night I was hanging out with friends, and there was a freak accident where a gust of wind sent a half-full can of soda all over the place. My computer was moderatly splashed with soda, and it pretty much freaked me out. My last MacBook Pro had glasses cleaner spilled on it and it costed me $500 for a new logic board. After wiping it down I realized that over time the soda could corode the internals and I'd be screwed. I have basically no money and I couldn't afford another mishap like this. Today I went to my Apple Store, and explained my situation - honestly. The Genius tried looking at my keyboard problems but he didn't notice anything different and said they were normal. (figures though, it was so loud in the store that he couldn't hear the noise) He then went to the back to open the computer up and see what's going on. He came back and said he found no soda, but he'd give me a replacement anyways. I was insanely grateful. I got home and found out I was very lucky. The replacement has both a Samsung display and SSD, just like my first. My keys are working perfectly. The computer makes no weird "clicking" noises, and feels completely solid. And also, my trackpad physical-click button is now firmer, in a good way. Basically, Apple's customer service seems to rock. I had another experience not too long ago with my iPhone 4, a Genius couldn't actually see my problems but he replaced it anyways. Just thought I'd share this, maybe someone will care!
