Leopard is installed.

It all went fairly smoothly aside from some difficulty with my old mail--the new version uses a different mailbox format, and didn't seem to realise my mailboxes were there. It was solved by deleting all the preferences and leaving nothing but the mailboxes folder in--then when I restarted Mail, it imported them all correctly.

I'm not entirely sure on the interface changes: the menu bar is now semitransparent and I find it a little annoying. We'll see though, maybe I'll get used to it.

I know, exciting. I'm a saddo geek.
