This device looks like an iPhone dock/speakers combo, but is actually a printer of 4×6 photos! Getting inb4 AirPrint on iOS 4.2, this device accepts photos from the dock connector using an app available on the App Store, which lets users take pictures in-app or choose from photos on their camera roll. The printing process itself is pretty interesting, with the exit slot spitting out the photo paper and then swallowing it back four times (once for each color ink) before finally regurgitating the finished product.

A product with a pretty limited scope of use, but it seems to be a good, semi-portable device to carry around if you ever need to print lots of photos from iPhones! Compatible with every single generation of iPhone.
