It appears to me that Angela's goal might be to either slim down Apple stores, or expand them in their existing space so that they remodel and take out the stock room, or perhaps both.
If you slim down Apple stores, you can have more of them and/or more easily embed them at other retail partners. If you remodel to remove the stock room and push online sales, you end up with a larger space to show off future (and expanding current) Apple products. I think that may be a serious concern as Apple dives into new areas such as wearables, has expanded the iPhone and iPad into multiple sizes (including a rumored iPad Pro), and is rumored to be expanding their TV-related business. How do you display all of those products at once in your front of house, while also having to make extra space in the stock area for direct sales? It seems like this is coming from necessity, and if so it's a smart move.
Their physical store would become a showcase for all of that stuff, how to use it, support, and then you can order everything online. Although honestly I wonder if they would stop doing even basic repairs in-store to make room. Apple could build large warehouses in each state and around different countries, much like Amazon, and ship products to customers in 1-2 days. These same facilities could also house repair centers and quickly ship them back to customers.
