This is somewhat a present-day Polaroid, an accessory for your digital camera to print photos on-the-go with a palm-sized printer.
Accepting its image data using PictBridge via a USB or infrared, it weighs just shy of a half-pound loaded with batteries and paper, making it kinda easy to carry around and ninja-print shots on the spot. It's $127, only in Japan so far.
Wouldn't it be easier just to e-mail the pictures to whoever wants one? Some people are still stuck in the printing era. At least Fujifilm could have added Bluetooth to this new model
It is kinda slow though, printing a photo takes up to 2 minutes.
