A quick sidestep as I needed to get some files up to share with my sister in-law so I thought I'd enable dropbox on this new desktop. Documented here as there seems to be some disparate inaccurate bits of info

sudo add-apt-repository "deb http://linux.dropbox.com/ubuntu lucid main"

sudo apt-key adv –keyserver pgp.mit.edu –recv-keys 5044912E

sudo apt-get update;sudo apt-get install nautilus-dropbox

I'm becoming familiar now with apt, and while I'm missing zfs and IPS from Opensolaris I must say as an end user desktop I'm pretty happy with Ubuntu and the integration with the rest of the world.
