It had to happen
Those of us who's dismissed the Chinese as "good at putting things together and maybe copying things" have never worked in technology and so seen first hand just how many high quality Chinese engineers there are. They're everywhere....and they're the ones that aren't living in the PRC. So its kind of inevitable that they were going to come up with their own devices sooner or later. After all, they're not only smart but they've learned from the best -- all that outsourcing gave them everything they need to know about manufacturing, marketing and distribution.
