Why is ARM interesting? Running android natively is one of the few things I can come up with...
But the interesting point is what kind of previously economically unviable projects are now viable.
I Tweeted to them and suggested that they offer -- at a possibly much higher price point -- a physically isolated server that must be manually provisioned by a human being. Any access would require multi-factor authentication followed by the actual dispatch of a person to retrieve the device.
This would be interesting for things like CA master signing servers, etc.
