The computer of the future

Imagine. It’s approximately the size and shape of a large cell phone. Heck, it basically is a large cell phone, they’ve got powerful enough processors. On the back is a big lense. Prop it up 5 feet or so from a wall and project your desktop. All you need a wireless keyboard. Imagine. You could compute from the woods, from a hammock, using a sheet stretched taut between two trees as a monitor. You could compute from a cave. From the beach. From an alleyway. Obviously it needs a heck of a battery, but still. And while we’re here, why not give it a telescoping radio antenna? Or whatever else. It could be anything. The future doesn’t have to look like the present.
