The photo gallery Mobile Burn put together of all the new Sony Ericsson cellphones introduced at CeBIT last week has a picture of what might just be possibly the silliest use of Bluetooth yet: to race model cars. Sony Ericsson built a race track with little cars that could be controlled remotely using Bluetooth-enabled handsets. Oh yeah, there are some pictures of some other phones in there too, like the amazing-looking A1101s.
