This was featured on NPR; they had a 15-minute segment all to themselves, IIRC. First time I heard it I thought it was a solution looking for a problem. The people they're targeting, fashionistas, derive a carnal pleasure from that act of shopping itself. Dressing a robot is akin to injecting nutrients in lieu of feasting on culinary delights.
Only fashionistas shop online?
I'd say their big miss right now is not having a "virtual sizing" model for women. As far as I can tell from their site, they've only got a male version.
