I'm considering selling my MacBook Pro (spec in sig) and my iPad 2 to buy a MacBook Air, which would cover my needs in one unit rather then two. The only gripe I have is the lack of FireWire on the MacBook Air. At the moment I create videos using iMovie, and all my projects and events are stored, and accessed, from my external FireWire800 drives connected to my MacBook Pro. I also daisy chain my FireWire drives, and it all works nicely. The lack of FireWire port on the Air would mean I have to use USB instead. Would the above editing with imovie work well over USB? Alternatively are there any thunderbolt to FireWire800 adapters I could use? If not I'll stick to what I already have as it all works great.
