Amidst all the new announcements today, Steve Jobs only mentioned the new revision Mac Mini in the Q&A section at the end of the event.
The new models sport either a 1.83GHz Intel Core2Duo or a 2.0GHZ, both have 1GB of RAM, and you get either an 80GB hard drive or a 120GB. Intel GMA 950 graphics remains unchanged. Oh, and you get iLife '08 with it too.
