However if were taking about x86 arch tablets or portable devices @ ~200 USD
then folks at AMD camp and intel camp must realize that the only person that can achieve this is AMD period.

it will be just tablet not dock or keyboard or shit, maybe even no OS or linux OS.
WHY ???
PPL intel CPU are always high priced, you want find a intel CPU to build with without costing you 100$ and upwards which is the half of the BOM (Bill of material).
Look at the surface, looks at samsung windows 8 tablets its all ~400 USD, i also doubt that AMD can make ~200 tablets maybe ~300.
