You’re thinking from a size perspective. I’m thinking from a capabilities standpoint. Today’s smartphones require very small electronics to pump out some impressive hardware capabilities for something so tiny. By comparison, we could get horsepower comparable to an enterprise server in a tablet. This would have immense implications for the current datacenter and consumer-level electronics.
Imagine 60”+ televisions that weight less than a pound, ultra-dense memory and solid state disk drives allowing for hundreds of gigabytes or even terabytes of RAM and possibly petabytes of disk in a solid state form, all in the same packaging of today or even smaller, entire rooms full of electronics compacted down to something the size of a phone or a tablet. The applications are almost unimaginable.
Ahh...good point.
