I just updated my Ubuntu from Dapper to Edgy. It went easily enough- took several hours, for most of which I didn't have to do anything, but every once in a while it would ask me about something (usually to do with some file I customized for some reason). In the end, I'm quite pleased, a lot of things are ticking quicker. It's not without it's hitches- I'm going to have to do some tweaking to get my webcam working again. I got the webcam (an older Logitech thing) from the cbc through a show called ZeD a few years back. I participated in an online/live broadcast thing and got to see myself live on national television (well, with a bit of lag time) while sitting in my room... but I digress ;-)

Overall I'm liking Edgy :-)

I made sure to uninstall the beryl eye candy stuff before upgrading, putting it back in was very easier- it's much more seamless in Edgy, but still a little off with handling multiple desktops- it does it, but it's kinda twitchy, so I only turn it on (which I can do now without having to restart my xserver) when I'm trying it out- might find a setting that will stabilize it...
