has anyone even considered this??

If Apple does indeed get it's 30% cut from these various apps and what not, ummmm, Apple is in California so guess what, CA sales tax on all purchases from California residents. I am very willing to bet money that the CA powers-that-be are salivating at this potentiality. Prior to this sort of scenario companies such as Amazon have no business presence in CA so CA residents, though we are all supposed to report and pay the taxes, never pay that sales tax. I am willing to bet that if these sales take place via Apple's iTunes store then
BOOM it's a transaction that has taken place in California. Sooooo, long budget deficit, assuming Apple stays in business more than a few years longer. A pretty safe bet either way.
