In the age of digital photography, how do you increase film sales? Fujifilm's clever bid is the Instax Square Link, a portable smartphone printer. It's essentially the Polaroid experience, with your smartphone's camera.

It is admittedly nifty that you can snap a photo, message it to your friend on the other side of the world, and then they can print it out (using the company's Instax Connect app).

There are, however, some contrived limitations to the system. Photos can only be printed via the app, a maximum of 20 times; they can be downloaded from the app a maximum of eight times; and the images disappear from the app after a month.

The Instax Square Link runs $140, and uses Fujifilm's Instax Square instant film, which run $20 for 20 exposures.
