Since mobile devices today have world’s more computing power than PCs of a decade or two ago, it makes sense that sooner or later a peripheral could double as an entire computer of its in, in this case putting that computer in a mouse and quite literally in the palm of your hand.

The Mouse Box by Przemysław Strzelczyk works as a mouse normally would, but contains a processor, storage, HDMI connection and wifi capabilities as well. As the one external computing accessory people travel with, this seems like the right type of device in which to put a whole computer.

The next step: creating a wireless charging mouse pad, since energy is likely to be the most limiting factor, as it is with smartphones. Hopefully a model further in the future could contain some kind of projection device, eliminating the need to carry a screen as well.

And here are the specs: 1.4GHz ARM Cortex CPU, 128GB flash storage (cloud storage optional), Micro HDMI port, Wi-Fi connectivity and 2 x USB 3.0 ports. “From now on,” says its creator, “you don’t need to buy a few devices to keep your computer always at hand. Mouse-Box uses the power of a mouse, an invariable component in a computer set for many years.”
