Dmitri Siegel has a priceless piece up on DesignObserver entitled "Lost In the Supermarket", where he looks at the "culture of design" in a kind of drive-by ethnographic assessment. Don't want to ruin it, but here's a quick sample:

For example, strolling through the aisles of the Supermarket you might think that our species was cursed with fingerless mitts instead of hands. The shelves are an eco-system of plastic ridges, fins and nubs resolutely devoted to the promotion of grippage and the eradication of slippage. Apparently men are particularly afflicted with the inability to grip: the more masculine a product’s target consumer, the more layers of ridges and grippers it contains. The faux-ergonomic flourishes on shaving razors could make them serviceable for a walrus.
