My original HD(160GB) was just to small to hold all of my Data that i wanted to carry arround with me, particularly all of my music and some parts of my iPhoto library. So i cloned my HD with superduper.
As soon as my new MBP arrives, I will move my new HD from the old MBP to the new one and feed it then the Lion OS through the OS DVD. Now figure out what you could do with an unused MBP and a brand new HD from Apple...$$
Piece. of. cake.
No technical advice. Just tidy up the desk on whitch you will do the HD Swap. Loosing a screw makes you screw up..
