They are a different class of product. I would not be surprised for apple to allow a parental control to lock a given mac down to just appstore apps. This is a nice feature.

Since steve jobs explicitly said this is not going to be the only way to install software, all this speculation is dishonest.

The funny thing is, he shouldn't have had to say that. You should know apple well enough (Rather than listen to the nonsense from the nondevelopers who are bosting page views by bashing apple) to know that apple would never force people to only buy mac software via the appstore.
