This. And I see no convenience in the App Store. As long as they can't even deliver a propper bill for my tax accountant here in Europe.
They start in this direction with Mountain Lion. It's just wrong to force people to have an Apple ID to use a Mac. I'm pretty sure the plan is to force everything to the App Store within the next couple of years. Which is a shame because I like Mac OS X and would hate to have to leave the platform ...
That is also EXACTLY the way Microsoft's Windows 8 and 9 are going to be like. So the only alternative would be... 10.4 Tiger!
