Last thursday afternoon I decided to take the plunge and upgraded my laptop from Ubuntu (Gutsy) to Ubuntu (Hardy), and as I half expected the procedure was not totally flawless.  I had the laptop in work so did the upgrade over ethernet, rather than risking doing over wireless LAN at home. (I didn't want to get part way through and find that the wireless stuff had changed).

So far I've come across 7 things that either don't work or don't work as expected. I'll be going through them in detail soon.
