Also you all should thank me for preventing a nasty patent, although it's pretty likely the company has already filed an application, don't you think? But there's the product described in a blog post four years ago. Makes it hard to claim it as a non-obvious invention.
PS: To people who say you have to be in your 20s to understand today's technology, here's some pretty convincing proof that's not true. In 2007, I was 52 years old, when I had this $41 million idea. If you're only betting on 20-somethings, you're missing out on a lot of goodness.
