Ricoh was showing off their G700SE at Photokina, and the updated version of the G700 is capable of using add-on modules like the GP-1 GPS dongle and BR-1 bar code scanning module. Pretty cool idea. It should give the camera a longer life as well as make it more versatile.
The camera has a dust- and water-resistant shell as well as Wi-Fi b/g and Bluetooth 2.1. It was designed for governments and enterprises, so it will cost you about EUR799 ($1,070) when it arrives in the first half of 2011.
