Dirty secret: I love Safari on Windows
It hasn't replaced Flock for me, but it's making inroads.
Afterwhen it first came out, I have to confess something: lately I've begun to rely on Apple's browser. Not for everything, mind you. But the more I use it, the more I like it.
The biggest reason: It's fast. It's faster to start up than Firefox, Internet Explorer, or Flock. And it's fast to load pages. Blindingly fast. Fast enough to make the Web feel more inviting.
I also like how it displays text. Sure it's using a non-standard font smoothing technology, but I think it looks great.
But when I need a Web page loaded up fast, Safari is often the browser I turn to.
