I am planning on getting time capsule when it is released and will be using it as a wireless external hard drive which will store my video library. I want to use the wireless feature to download videos (about 1GB each) to my macbook air so that I can watch them on trips instead of getting the external superdrive and taking along dvds. First of all, is this possible ? And if so, about how long to send a 1 gig file to the macbook air wirelessly? Thanks.
