One thing O'Reilly reads would most likely want to know is that the upgrade kills your installed Dev Tools.

I was able to reinstall the Dev Tools from ADC (still the old version), but I understand Apple has a new set they send out with the $19 upgrade (and I assume the $129 full version).

I have not fully tested the reinstalled Dev Tools too thoroughly, but it did compile a simple C++ and simple Java app.
