Just when I thought the ultimate decadence was shopping at my home computer in my PJs, they come out with "window shopping" -- literally.

At Polo Ralph Lauren's flagship location in NY, customers can tap on the huge store window which has a projected image of a Lauren tableau. All 67". A "thin touch foil" mounted on the glass powers the touchscreen. Tap what you want -- those rustic suspenders, say -- and swipe your credit card on the wall-mounted card reader.

The company will experiment with this through Sept 10 and then evaluate it's success - or failure.

Talk about an impusle buy. This is just plain dangerous.
