And what's up with all the cassettes starting with 10 tooth sprockets. Smaller sprockets have greater energy losses, so you're leaving some energy behind when you use these cassettes.

One of the articles I saw said the SRAM folks say the things work out you don't really lose anything in terms of efficiency. Of course, you do lose the ability to run the wheels you are used to using unless SRAM 12 works with Campy 12 cassettes. Also, the SRAM folks may be a little biased in this regard.
