Yep, but that may be a bit spendy also.
I agree, USB 3 seems pretty quick for most storage needs IMO. I do prefer the drives where you can upgrade the connector such as the Go-Flex or Backup-Plus line of drives, although they do cost more.
That also reminds me, is it now possible to set up a Bootcamp drive over TB, or are you still limited to using an internal drive? That would certainly make my life easier and lighter when I get my new MBA.
