Again, I call ********. Most users don't have the slightest clue what a repository is and will likely never even enable Extras on their devices. Problem is, the ones who will go seek out additional software are largely coming from Windows where downloading random software from the internet is how it's done, and this mindset will get them in trouble.

Nobody's arguing that there should only be one repository (some things clearly don't belong in Extras-- although I don't buy your CUPS example for an instant since that's a package that shouldn't be in user/ anyway), but having the majority of the software for the platform available from a stable, centralized location clearly benefits both users and developers, so let's keep the silly and non-sensical iPhone comparisons out of it.
