One thing I dont understand is Intel/AMD have x86 license, they could have build a low power USB x86 PC to run win9x using a slow SoC. If ARM can run Quake 3, I think x86 that is less efficient are still well enough to at least run window9x.  I am pretty sure a lot of x86 softwares have req much lesser than Quake 3 

Someone from these 2 companies need to copy this with some brain, u could sell this thing very well.

just imaging a USD size PC with a build-in wifi connection + a usb connector for storage + necessity connectors like audio jack/hdmi port. That allows u to plug into a TV and turn into a PC itself.  Or may be plug multiple on my desktop to become 1 big + many mini PC running diff OS like old Linux.
