The first psp gadget I ever bought was the PSP Go Cam. Its a simple plug and play camera that fits on your psp's usb slot (the one on top). It's a simple and humble gadget to have on your psp and only offers a 1.3 megapixel image. The pictures you take (on a sunny day) are a perfect fit on your psp screen although can be a bit pixelated when you view it on your computer. The night-shots can be a problem because the camera does not have one and your pictures come out quite dark. Though in day shots, the pictures look great and the cam even offers some effects like sepia, black and white, warped shots and others. You can also take videos which are perfect for viewing on your psp. All in all, its a fun point and shoot camera at the convenience of having it on your game console.
The downside on it is that it only fits the old generation psp consoles (psp fat, slim 2000 and 3000). The device is not suitable for the new PSP Go.
Here are some of the pictures I took with my psp go cam. You can click on them to see the actual size and resolution on your computer or browser.
Here's a video I took with it too:
