To clarify: the warehouse and the showroom would be separate but contained in the same complex (much like Ikea). Each person has an app on their phone to record their purchases while browsing the showroom. When the shopper is done some items are retrieved robotically for them to pickup while some items (or all items - it's up to the buyer) are delivered later in the day. I don't believe the robot technology is quite yet up to this. But in 5-10 years it should be. This setup would feature primarily first party products but it would also be possible for third party products to be on display in the showroom (to be delivered later from a different location). I agree that Apple-sized showrooms with mid to high-end first party items would be the logical first step.
