Cool, except the audio and video don't sync. Watching the Matrix was like watching French noir film dubbed back and forth to English about six times. OS 9 is not compatible with Edit DV, or Final Cut Pro. The only tool that works is iMovie. Not a good thing.
Some features are very nice.
Sherlock 2 is a great search engine, an outstanding upgrade from the original. Drive indexing and the ability to select drives are noticeable improvements. The new OS has a software update feature that looks for drivers and updates automatically. It even works, most of the time. And the new security features are long overdue but welcome additions.
