I just picked up a week 12 MBA 1.6/80GB from the local Apple Store. So far everything is working great. I bought up one from the original batch of MBAs a few weeks ago and returned it due to a few issues. I figured that Apple may have the build process down a bit better by now so I decided to go another round. Overall, the machine seems to be running a bit cooler. Right now the the temp is hovering around 42C doing general work. The fan is obviously silent as usual. Build quality is excellent as it should be. I did play some Youtube videos earlier and the machine stayed cool and quiet, which was not the case a few weeks ago. One last tidbit is that my display is a 9C6F which I have not seen anyone mention yet. This display looks awesome. The colors are quite vibrant and saturated with no noticeable backlight bleeding. Anyone have a clue who makes this display? I would definitely add it to the list of good displays.
