What's That?: Adding Dead Weight
This added material doesn't appear to serve any other purpose-the components don;t generate much heat and there's no noise to dampen. My conclusion is that while the components on the PCB (other than the connectors) where not all that tall, the connectors were. So this drove the final thickness of the product. I guess when you're spending $100 on a piece of video kit, you probably want it to feel somewhat solid in your hands. So this is a cheap way to add some "heft" to the product.
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
