Seriously considering the 13 Air w/ 4 gig. Should I get a usb optical drive to go with it? How easy and fast is it to use the wireless optical option when loading dvd media on to the Macbook Air? Curious to know if I can use this Macbook Air as a portable workhorse without having a portable optical drive to load stuff onto the Air. Finally, I have a Sony portable USB DVD drive. Will this work with a Macbook Air? I don't want to buy a Superdrive if I don't have to.
