Wow! Apple certainly wants more people to sign up as Mac developers, that's for sure. In changes made today, the ADC Premier and Select tiers have disappeared and they have been replaced with Mac Developer through the current developer portal (which has the iPhone developer sign-up as well). Mac and iPhone are now $99/year each and doesn't include the hardware discount, which has been an historical benefit of the more expensive developer program. More importantly, you can't buy the Premier version, which includes your ticket to the next WWDC, so you'll be fighting the crowd with everyone else.
