The Padcaster is one of those accessories that pushes the Apple iPad beyond what most people do or would think of doing with it.
For however ridiculous it may seem to some people, plenty of iPad owners use them to take pictures and shoot movie clips. Not everyone wants or needs to produce professional results, but that's just what the Padcaster makes easier.
So, no, this case isn't for everyone, but if you use an iPad to shoot and produce Web video, it's a perfect fit. And, while its $149 price might seem steep, you get more than just the case and it can be used for more than just recording video with an iPad.
Basically, the Padcaster is a two-piece iPad case made up of an aluminum frame with a removable urethane insert. Though the insert is flexible, it fits tightly around an iPad, so there's really no chance of it accidentally falling out.
The outside of the sturdy aluminum frame is lined with 1/4-20 and 3/8-16 threaded holes for attaching lights, an external mic, or other camera gear. Just attach your camera in the middle and surround it with your favorite accessories.
With a bunch of accessories attached you'll probably want to use it on a tripod or some other support, but the frame is wide enough and heavy enough to stand on its own for shooting or viewing. Plus the size and weight of the frame makes handheld shooting more comfortable, giving you a better, steadier grip.
