Last night I finally moved my last (and main laptop) system up to Ubuntu 7.04 (Feisty). The install was painless. Started up the Update Manager, clicked the button to upgrade to 7.04, waited about 40 minutes where I also had to click Ok/Accept/Forward a couple times, and that was it.
I upgraded for a few reasons. First, some things I wanted to get working on my laptop were (supposedly) easily fixed in Feisty, but still overly complicated on Edgy, including using Silc/Tor with IRSSI and OpenVPN client management. Second, I believe in keeping software as updated as possible (within bleeding edge reasons, of course). You don’t want to ever be left behind with unsupported (or unloved!) software that has reduced functionality. It’s a lot like living in the past.
