Im not sure i cant wait any longer for the 7200 500gb drives to be ava. Im considering getting a mini and upgrading to a 320gb 7200 drive, and then getting a 500gb external drive for downloading HD movies, tv-shows, etc. I would then keep the mini "lean and mean" for OSX, fotos, home video editing, etc. The external would be constantly attached to the mini, not sure how i feel about that though (from a estetic viewpoint) Is this a good way to go or should i just wait a bit longer? What external drive would you recommend?
