I have a theory.
I expect these ad's will show in the version of OS X that Apple plan to release out to other OEM's later on.
Think about this for a moment.
Apple have already released: Drivers (every i support), iTunes and Quicktime for windows. Ad they are crippled and very slow indeed!
I think Apple will release a version of OS X for the Pc platform but, like iTunes and Quicktime, it will be crippled and slow and full of ad's.
Why full of adverts? To make the thicko's think "hmm, this is filled with ad's...i need to buy a mac, i'll have no ad's on that"
Would Apple do this? course they bloody would. You lot keep forgetting, Apple don't give a **** about us customers and loyal macheads, they're a company, a business and it's about time some of you learnt that and got it though your thick heads that Apple don't give a flying **** about any of you or me!
I honestly don't see any other reason to patent this.
For that person who said "maybe they're doing this to stop other companys doing this" - Are you serious? Apple don't give a damn about others either
