would this be compatible with a g5 imac? i would find it hard to believe it is ONLY compatible with the macbook air.

Well that's what Apple is saying. We'll have to wait and see what it's status is after it starts shipping...

This straight from an Apple rep:

"I can confirm it is only for the MacBook Air; the Air has special
hardware support for it. (I suspect the USB port provides more power,
but I don't know if it is anything more than that). There is also the
driver for it in the boot ROM of the machine to support booting from it."

Buyer beware.

I think this would sell if they opened it up so that people with combo drives could buy this as an upgrade.... My thinking is that a rom update and software update would be needed to do this. Maybe Apple could handle this like they did with the wireless n enabler $5 thing.
