@But will wireless work out of the box?

my experience of using a lappy with broadcom air-force-one card is:

* pre-gutsy I couldn't get wireless to work, but with gutsy it was able to recognise that I needed a proprietry driver and helped me install it.

* An upgrade to hardy broke it and plain ethernet too, so I reverted to gutsy.

* Intrepid behaves like gutsy, so I've been using that.

Hopefully Jaunty will continue to work, if not Intrepid is still nicer than windows.
