The hard drive on my laptop was doing some weird things on occasion and I decided to get a new one and an external case to stick the old one in. Figured while I was going to be replacing my hard drive I might as well install Feisty Herd 5 and use that.
Installation had no problems. I was up and running with all the updates in 3 or 4 hours (I have a slow Internet connection and there were a lot of updates). I fiddled with things to get Beryl working mostly because I want an Expose kind of thing, but ... it was really sluggish (I've got a Gateway 450ROG with an ATI Radeon Mobility 7500) so I removed it.
Everything looks good so far. Figured I'd mention it in case anyone else was thinking about Feisty Fawn.
Update 3/19/2007: I traded emails with Patrick and he helped me configure aiglx correclty. I've got Beryl 0.2 working very smoothly--some of the features it has are already making a huge difference in usability. w00t! Also, there's an article on Ars Technica that walks through Beryl features called Bring on the bling with Beryl. That helped, too.
