One WWDC addition

Oh yeah - Safari 5. Book it. All the goodies in the Webkit nightlies, wrapped up in a pretty bow.

More seriously, there won't be a MacOS release this year, so it's good timing for a standalone Safari release (after all, browsers are the computing experience to a lot of users). Plus Chrome is right now pretty much the canonical WebKit-based browser and has a lot of mind share. WebKit is Apple's baby, and there's no way that'll be allowed to stand. Apple is happy to see WebKit adopted by so many vendors (less chance of IE being required by websites that way and it also helps kill ActiveX), but there's a pride of origin there and Apple also wants to be the "reference implementation" of WebKit.

Hence Safari 5.

For more details, the usual rumor sites have a listing of what's expected to be included in the Safari 5 feature set.
