I suppose a partition means that you dont have to lug around a seperate drive if you travel a lot. Make sure any VPN applications work ok. You can backup and re-instate your previous apps via command line; To backup Code: sudo dpkg –get-selections > myPackages To re-instate Code: sudo dpkg –set-selections < myPackages && sudo apt-get dselect-upgrade You can also do it through synaptic One word of warning if you do install to a external drive it is possible to screw up grub on your main drive, I did it, dont know how, but managed to stumble through the recovery. Next time I will slide out the internal hard drive and do the install with the USB drive then just to be absolutely sure. Mark
