Here is a transcript w/ pictures of the entire keynote summarized over at Engadget.
The gist of it:
New Mac Mini with 2 different versions
"We have two models, 1.5GHz Intel Core Solo, 512MB RAM, 60GB hard drive, Combo Drive. $599. Second model is 1.67GHz Core Duo, 512MB RAM, 80GB drive Super Drive. $799" - Steve Jobs
Some new mac software announcements that have to do with OSX.
A new iPod accessory. Now I know there are tons of iPod accessories out there but they are all made by 3rd party vendors and very few are made by Apple. Naturally, when Apple releases one theirselves it gets more news because its usually very welll done/expensive.
The iPod Hi-Fi. Its a boombox you can plug your iPod into but its like the Bose equivalent of one. 250 watt output or something of the sort etc etc. Retails at 349$.
