Maybe one day they'll release an update that makes them as fast, or faster, than than the old models

Installed without a hitch.

A bit of a long shot...but has anyone that has the display lines issue noticed an improvement after this update?

this may just a placebo and my mind is playing tricks on me, but it immediately feels like it's running cooler and less loud! im on a MBA rev. A

My CPU temp is 108ºF right now... don't think I've ever seen it that low. You may be right.

So as much as I don't want to be that guy who installs an update and claims it fixes undocumented problems, my rev.A Air does seem to be running better.

My temp still runs really high, but while usually my laptop gets unusable if I watch flash video as the kernel_task steals all my CPU cycles right now it is multi-tasking nicely despite the flash video playing.

Mine is only weighing in at 422 KB. I wonder what the difference is...

If this means new (mid 2009) batteries are compatible with late 2008 Airs...
