It is funny that you should mention that. In the original press release they just said powered by an A9. I specifically asked them if it was an ARM Cortex-A9 and they said if was an ARM9. I too doubted that that an ARM9 would have the power necessary - especially for the graphics.
In cube and office environments, running three users' 'PCs' from one box would immediately appeal. What happens with proprietary software licensing and 'dongling' might be a different matter in such an alien environment.
Should be OK with network licenses of course.
Poses an interesting question: presumably Microsoft's OS and application licensing and DRM layers can track the hardware well enough not to get confused by this virtualisation?
Although Linux would have few issues I am not sure how many people are using it. There are many ways to run multiple users with linux platforms for office 'farms'.
The marketing people tend to get confused by stuff like that. I expect it is a Cortex A9
Remember the Dilbert cartoon about "it's beige and you plug it in."
As for power, being ARM it is going to be way, way less than a third of the power if compared to a regular PC.
