There isn't much to review with the BitBoy, it works well by emulating a printer for the camera. It puts the photos on an SD card which is easy to empty onto a computer. It is easy to use and works as expected. It is a little pricey for it's functionality, but it seems to be the only thing on the market that can do this task with ease.
The Gameboy Camera is as weird as it ever was. I can take these hard to shoot photos that range from halfway visible to completely unreadable. I then can stamp goofy things on them, including select Pokemon Red/Blue sprites, and add a frame. It does about as much as you'd expect for that era with a little bit more.
If you're looking for a cool lo-fi camera, you can pick up everything you need for around $100, but you'll have to wait and see if there is a second batch of BitBoys coming.
