Before a new product is released, I always see people have it days, even weeks, before it is released to the public. I know that there are people who test the product out and I wanted to know where/how I can sign up for it or contact Apple about it. Thanks for your time!
There are no formal beta tests for the hardware. Media gets things early in order to provide plenty of press or they report on seeing pre-releases of the hardware at various MacWorlds or Developer Forums.
