Ubuntu has been working pretty well on the desktop and the laptop here. A couple of "issues" i've found are:

1. Mysql server on the Ubuntu 64 server seems to corrupt the db, host, etc tables. This means mysql doesn't start anymore and requires a rm -f /var/lib/mysql/mysql/*, then a dpkg-reconfigure mysql-server-5.0 to get it going again.

2. Network manager. Why does my eth1 interface keep coming up and creating a default route, sometime huors after bootup? It seems to be ignoring /etc/network/interfaces now, and just doing its own thing. Weird.

3. Swiftfox (32) and plugins are pretty much required to view flash etc. ;-(
