The folks at iFixit have managed to get their hands on a MacBook Air and taken it into the operating theater for a quick but very thorough autopsy.
Some interesting points to come out of the dissection:
The redesigned MagSafe connector
The fact that the lower half of the MacBook Air comes apart pretty easily but that the screen section is well stuck together
That to replace the battery yourself you'll need to tackle 19 screws (fortunately, the battery cabling is attached by a simple connector)
Components appear to be well protected from shock
The multi-touch cpntroller is the same as used in the iPhone and the iPod touch - the the Broadcom BCM5974.
The well-designed wireless antennas
Well worth taking a look at! I should be getting my hands on a MacBook Air soon, but I don't think that Apple would be all that pleased if I gave it back in pieces!
I am still left with one question thought - will it blend?
