It's a great way to back up or transport large files (digital pics backup, email, address book, etc.)

Uhhhh ??? - So is FTP.
And it's a heck of a lot faster than ( j ) emplode.

FTP does 'bout 8 Megabits/second on my setup through a 5 port switch.
That's 1 Megabyte / second, nearly double the speed of a sync,
plus no need to rebuild the DB, which takes about an eon with all my playlists.
