Here is a first for an Android camera with interchangeable lenses, and it is from Polaroid. Based on the source, there are not much information except that it has a 18.1-megapixel sensor, 3.5-inch touchscreen, pop-up flash, Wi-Fi, HDMI and Android 4.0.
I think the trend of using Android as the UI for camera is getting popular nowadays. We have seen Nikon, Samsung joining in the fun. Hopefully, we can see more of such camera as pictures become more creative with software.
