The lack of the feature to use a Mac or PC as an AirPrint proxy for the iPad will accelerate the creation of AirPrint-compatible printer firmwares by printer manufacturers, who can no longer ignore Linux compatibility - let alone the iPad compatibility. Once they issue such an upgrade, their printers will support AirPrint natively.
Another positive result of this new development is the fact that I won't to have to buy a brand spanking new Intel i7 based $2000 iMac to serve as a central computing hub for my household and to be used as an AirPrint and AirPlay proxy. Spending $2000 just for AirPlay makes no sense. I will continue using MacBook and MacBook Pros in my household to stream to the AppleTVv2 and I may have to spend a few hundred dollars for an AirPrint-compatible printer if the manufacturer of my current printer (Samsung) drops the ball and does not release an upgrade to their firmware that supports AirPrint.
