Not at all, except when a company disguises off-the-shelf components to add some sort of "high end" cache to their product. For example, I have trouble believing that Colorfly and Rockchip "codesigned" (as you say) the processor. Really? So Colorfly can custom design a system processor and then have that design fabricated for their exclusive use? That's quite an accomplishment.
Wouldn't it be better to say that Colorly asked Rockchip to add some lines of code to the instructions of an existing processor? I have trouble believing even that since Rockchip has a hard-won reputation for lousy customer service. All those deeply ingrained bugs on any given RK device isn't the manufacturer (Teclast/Nationite/Pasen/Oppo/Window/et al.), it's Rockchip.
And what of these magical "C4" amplifier and "Colorfly SPU" chips? It seems the Colorfly does video, so the "SPU" could be something like the Rockchip RK1000 to handle TV-out function. The C4? Who knows...Maxim?
I think you mistaken what I mean by 'co-design' (and by 'C4', I mean the whole DAP) - it is very common place for DAP maker to ask Chip provider to customize the standard solution they have to fit the DAP maker needs. Usually it is accomplished by the DAP maker sending its own tech people to the Chip provider company with full design spec, then the DAP maker engineer will customize their standard design with the DAP maker's tech and together they come up with a PCB design. Then the Chip provider will makes the PCB with only the basic controller chip (and its associated components) soldered, send the half finished PCB to the DAP maker so it can finish soldering the rest of the components itself - that's how the 'co-design' works and it is a very common industry practice that is not limited to Rockchip, but almost all other Chip solution provider as well.
Also, remarking chip isn't something new in the electronic industry - it is done so in order to protect the design against clone and it has been a practice for a long time, way before China is ever big in electronic or Colorfly comes to existence. Just because most people do not know about it doesn't mean the industry isn't like that before.
As for firmware - whether Rockchip or ColorFly can come up with something half decent is another matters on its own. If they can make a cheap part works like wonder, all the better for them; but if they use the most expensive chip around and still have a cr*p firmware inside, what's the point? It is the overall performance of the product we are buying, not individual parts.
