Apple just announced new iMacs. They are aluminum and come in 20" (two models) and 24". There's a new view called "Events" in iPhoto that should make it easier to deal with large photo libraries. Apple's .Mac service is enhanced with .Mac Web Gallery, which integrates with the new iTunes and also the iPhone. It's a Web 2.0 app now. And iMovie is being replaced by a completely new app of the same name. Steve Jobs claimed that with it you can put together a 5-minute movie in 30 minutes, and he demo'ed that from the stage. iWeb, iDVD, and GarageBand get new features too. And .Mac subscribers get 10 GB of storage. Here is Engadget's blow-by-blow coverage, and Wired's.
