If you're in Paris this week, and are underwhelmed by the centuries of culture, art and architecture muddling up the place, you could do worse than reporting to the 2010 Paris motor show. If you choose to do so, you'll have a chance to take a gander at some of the most advanced transportation technology in the world. If you're an Apple fan (and if you're not, we have to wonder why you're visiting our site: glutton for punishment, perhaps?) you'll want to pay particular attention to some of the wheels brought to the show by BMW and Mercedes. Both companies have opted to use the show to show off prototype scooters that utilize an iPhone not only as a key but also as the only user-interface element outside of the handlebars.
