The Jackito PDA, which they’re calling a TDA (Tactile Digital Assistant) because it uses only the thumbs to control and no stylus, has been announced by French company Novinit. It has in interesting internal architecture, with 7 parallel processors, allowing speed and power savings. They claim that a single AA battery will last a few months. It runs an OS called 3ActilOS but the site doesn’t have very much information on it. The images on the web site look like Photoshop jobs, so we’ll be interested to see if the $600 machines that they’re selling actually exist.
