The biggest news was that they're already selling Intel Core Duo based machines now—months ahead of schedule—in the shape of a revamped iMac (“only” the CPU has changed…) and the all new PowerBook successor, the MacBook Pro, complete with built-in webcam, SATA disks and ATI Mobility Radeon X1600 graphics card. It is claimed to be 4× faster than a G4 based Mac like mine. Hot stuff.
On the software side of things iLife '06 and iWork '06 was announced. iLife '06 includes a new website/weblog generating tool named iWeb (of course) and iPhoto has recieved the attention it needed. iWork is still just Pages and Keynote, but both applications have gained vector drawing and spreadsheet-like capabilities. Both iLife and iWork costs the usual 79 €, which is really amazingly cheap.
The update of Mac OS X to 10.4.4 was also announced. I ssh'ed to my laptop at home from work and ran softwareupdate -l for a list of updates, then softwareupdate -ia and it installed all updates and asked me to reboot, which I did. I like the way you have nice GUI and complementary commandline utilities for the same task on Mac OS X, all built on a sane UNIX environment.
