I'm hoping the new Developer tools will be available for download after a month or two (assuming I can last that long), because I'm going for the free visit to the Columbus Apple retail store. I seem to remember something similar with the original release of OS X.
As for wget being replaced by curl, I'm glad because I've found I like curl more. I installed with Fink about a month ago, just because I could, and at least visually, it is much nicer.
