Seeing as tablets and phones are getting thinner by the day, why not make a camera the shape of an old Polaroid photo?

Dual cameras on the front and back, a single button, and a touch screen. It’s pretty much a phone minus the apps and connectivity. Why would it exist? Hopefully it would be an inexpensive option like a disposable camera. Plus it would be for people who’d like a nostalgic device.

Besides a micro SD card slot, one (optional) feature it would have is “shake to develop”, where images would slowly come into view, but would appear quicker if the camera is shaken (would require a gyro device within).
