'Buying Adobe Photoshop CS6'

Pat Dryburgh, after happily attempting to purchase a copy of CS6 once his beta was up:
"I’m no expert at payment processing, but I’ve bought a thing or two on the Internet. Some of these things have been software applications, and some of those have been from indie development shops run by a single developer. Each of these experiences has been flawless, allowing me to use the software within minutes, if not less.
And yet Adobe, a massive company with thousands of employees, can’t process an order sooner than 24 hours?"
My experience with software companies outside of Adobe has been much the same; I can't recall a single occasion where I've had to wait longer than a minute or two before my order has been processed, even for games. Yet in the case of a product that is actually relied upon by many thousands of people to do their jobs, there is a wait period of a day or two? This seems arbitrary and thoughtless, if not straight-up unprofessional.
