This is a pretty lazy foray into minimalism. It should be about breaking the product down to it's most basic components, not just removing the background layers of a psd.
Isn't it more of a design exercise that shows how removing background layers of a psd affects brand/product impressions? It's a thought experiment, not a marketing pitch - using a very simple idea to show some interesting variations on brand image.
Removing any image and leaving text isn't much of an experiment, let alone exploration of minimalism.
