Safari 5 has implemented geolocation (as already found in Mobile Safari, and Snow Leopard in general.)

Steve Jobs mentioned in his D8 interview that they take location privacy very seriously, and the ‘don’t ask for 24 hours’ checkbox is nice evidence of that; there’s no ‘Always Allow’ option.

Of course, I’d still like to see disclosure granularity at the source—ala Fire Eagle—but this is an improvement on the ‘OK/Cancel’ interface that the iPhone throws up.
