What "percentage" will they take on freeware and shareware (which makes up about 60-80% of my Mac downloads)??

Or will these be the "podcast price" items of iP/iPT software.

This is an entirely new computing platform which has captured the imagination of millions, and I expect much of the innovation will come from dedicated small shops and individuals providing simple but highly innovative and useful new small single purpose apps.

Will Apple embrace them or shut them out??
