With a new Javascript runtime, this browser does seem to be a lot faster with Javascript-rich sites. Try it yourself, but one warning: it overwrites your Safari 3 installation but the uninstall program works fine (I have done two complete install/uninstall cycles with no problems).

My computer use time is increasingly in the browser now, except for doing software development, some writing, and editing photos and video. Having a “snappier” web browser experience is great!
