Turns out that -it's very difficult for medium-sized businesses to design lower-cost products -because the only cheap processors (almost always from China) do not respect -Copyright law, provide almost zero documentation, and even Intel processors -are known to have spying backdoor co-processors in them? - -## Well what we do is... - -Well, what we do is: design 3D-capable efficient processors based on -full transparency. All source code, right to the bedrock, hardware -and software. We don't tell customers "trust us", we say "go have a -specialist audit the full source, independently".

"Computer Card" has the data *and* the apps on -it, so goodbye file incompatibility: just move **the whole computer** from a -TV slot to a Laptop slot to a Tablet slot to a Desktop slot.
