For those of us old enough to remember the glory days of Infocom, this comes as wonderful news. I really look forward to revisiting the game and seeing if I still remember how to win (probably not). As an aside, I'm pretty sure I still have a copy of the game for the Commodore 64 somewhere in my basement.
The biggest announcement for me, as someone who hasn't upgraded to Leopard yet, was the Mac Box Set (store.apple.com). It's a bundle containing Leopard, iLife '09 and iWork '09 for $169. Hopefully the education discount will be applicable.
