Let me start by saying that I am very excited about today's announcements. However, I was hoping for a little more than 500 GB in the expandable storage area. How long (if ever) do you think it will be before 750 GB and 1 TB drives come out? Should I pull the trigger now and risk being stuck with a useless 500 GB drive when bigger models come out? Can an eSATA such as this be re-formated and used as a regular external storage drive on a computer? If so, then it wouldn't be a total waste if a newer, larger model was released.
