I’ve uninstalled Apple’s Safari 3 beta, and gone back to version 2, at least for the time being.
The new one has some nice features, is noticeably faster, and has better JavaScript support. But it’s also definitely still a beta, and crashed a couple of times, and seemed to have one or two interesting side-effects on things like iChat.
I find it interesting that, only a few years ago, a web browser was just an accessory, where it’s now the most important app on my machine and needs to be pretty solid. But that also means I want a good, fast one, and this looked very appealing, so I’ll be upgrading again as soon as the wrinkles are ironed out.
