John Gruber on Apple's just-buy-our-devices-and-look-at-all-the-cool-shit-you-get-with-them model:
Microsoft’s model was: you’d buy a device, then pay for licenses for Microsoft software. Google’s disruption was: hey, you don’t need to pay for Microsoft software if you’re willing to put up with our non-blinking mostly-text ads. Apple’s model is: you don’t even need to see those ads, just buy your devices from us.
Interesting that he says "was" when referring to Microsoft and Google, and "is" when referring to Apple's business model.
