The more I use the Mac OS X Public Beta the more I am impressed with it.

A couple of weeks ago I joined the ADC Select Program. That usually costs $500 for a 1 year membership. Apple has a promotion on right now that makes it only $400.

This promotion ends TODAY. If you're considering Mac OS X Development, I encourage you to sign up.

It's a really good deal, and right now it's especially sweet because Apple includes the OS X System Overview book and a nice OS X T-Shirt in the orientation package.

Of course it also includes the OS X Public Beta and the OS X Developer Tools CD. (note the Developer Tools will be available for free download in mid-October)

Another benefit is being able to purchase WebObjects for only $399 intead of $699. Metrowerks tools are also discounted, as are WWDC passes.
