I’ve been very happy using Safari most of the time.  When designing web pages, it does a very good job of rendering the layout (after all, it is Acid 2 compliant, but only in a every specific sort of way).  I have only one complaint.

The built-it pop-up blocker is actually quite good.  It does a good job of blocking unwanted pop-ups and allowing the wanted ones (the one’s you click on something to launch them).  The thing that kills me about it is that it doesn’t give any feedback when it blocks a pop-up.

Both IE and Firefox put a bar at the top of the page that alerts you that a pop-up was blocked.  This is a nice feature so that you know when you click something and nothing happens, you can see that a pop-up was supposed to open, but the browser blocked it.  Safari does not offer this.

This has only really been seen when a site uses Flash and launches a pop-up through a Flash link.  Some sort of visual evidence that a pop-up was blocked would be most welcome.
