With Snow Leopard (Mac OS X 10.6) on the prowl, no cruft is safe.
At this moment, the time is 11:38 AM Mountain Time. Just over two hours ago I picked up a copy of Apple's new Snow Leopard version of Mac OS X. Since then I've relocated to a usual haunt, sipped down a great latte, and installed Snow Leopard and the new Xcode, as well as updating all of my 3rd party applications for which a new version was available. All without a single glitch.
