PC Magazine reports: "What weighs just over a pound, nearly fits in the palm of your hand, and was just introduced by Toshiba? If you answered 'Toshiba's new mobile projector,' you're right. The TDP-FF1AU, from Toshiba America Information Systems Digital Products Division, weighs 1.1 pounds, measures 2.2 by 5.5 by 4.0 inches (HWD), and comes with a lithium-ion battery pack that adds 0.6 pounds and just 0.8 inches to the depth. According to Toshiba, the battery pack is good for 2 hours of viewing. If you need more than that, you can use the power cord."
Personally I would love to play with one of these devices just to see how well it works. I can think of a lot of cool applications for such a device.
For example: My Dell Axim 51v, can put out a 640x480 VGA signal. So I could put a video on SD card or a CF microdrive and have a totally portable movie projection system.
