All of the music I have, and it's pushing on towards 40Gb now, is on the laptop hard drive and backed up in BT Digital Vault. It's also on the iPod too, of course. The logic is...iPod to listen to, laptop to 'manage' the files, BT Digital Vault to safely store it all. Three locations is overkill, I know, but it's akin to boats with tubes, lifejackets, lifebouys, rescue lines, etc. After all, 40Gb of downloaded music is...a fair bit of money.
I've played with external hard drives but the beauty of a laptop is that it's compact and portable. If I start throwing in external hard drives on top of the - for me - obligatory man-sized mouse (I hate laptop touch pads) and charging cables, it starts to become more messy. I guess I thought that a big internal hard drive (250Gb?)would allow me to go to sleep on the issue for a couple of years as wherever the laptop goes, the folders and files go.
Unless, there's a body of persuaion otherwise
