Okay, I went ahead and made Safari my default browser. I guess what's cool is that every time I look up I'm finding another cool feature I hadn't noticed, like how pretty links are when you drag them in the page. There's YASR here that hits on some of the nicer stuff.
(addendum: Looks like (Saturday morning) they just posted a new build. I know there are lots of changes happening in their rendering engine, so I hope they continue with the quick updates. I'm not expecting nightlies, but weeklies would probably be A-OK, at least until it goes final)
The grave’s a fine and private place,
but none, I think, do there embrace.
