Yep! You beat me to it. I wonder if it would be possible for some big brands like Dyson, Samsung, etc. to band together and maintain the retail show rooms. Perhaps a new holding company could be formed to manage the real estate on a more "Walmart" like 2-3% margin with the HW companies bearing most of the cost of retail, but also gaining a much larger chunk of margin.
I think retail is going to become a very interesting space over the next 10 years as the Big Box model gives way to an Amazon same day solution on one side and a high touch, high service model on the other.
