John Gruber, back in 2007, wrote about the pre-orders of Leopard via his Amazon affiliate links and the breakdown between single-license copies and family packs. Nearly a third of the sales John saw of OS X were for the family packs, despite the fact that most DF readers were surely aware that Apple did not require any code activation to install the OS. In short, those who knew they did not need the family pack to install Leopard on multiple machines did the right thing and bought it anyway.
It’s encouraging to see Apple taking the same attitude and trust towards the customer that they used with OS X distribution and applying it to their retail stores with the EasyPay system.
