Microsoft showed off a whole range of new PCs and devices running Windows 10 at Computex 2015, but one that really caught the eye is the Quanta Compute Plug, an entire PC integrated into a power plug the size of a phone charger.

The Compute Plug comes with two USB 3.0 ports and an HDMI port, allowing you to easily connect the device to a TV or monitor and use it as a HTPC. Microsoft says the Compute Plug can be controlled using Cortana and a Bluetooth remote or headset, and presumably it will run any Windows home theater software that you like.

Quanta hasn't stated what hardware is inside the Compute Plug, although considering its form factor and power constraints, we imagine it's pretty low-power, probably using something like Intel's Bay Trail SoC found in cheap Windows tablets or Intel's own Compute Stick.

Another interesting device Microsoft showed off was the Foxconn Kangaroo, a very small form factor PC that packs an Intel Cherry Trail processor and a "six-hour battery", allowing you to easily turn a TV into a fully-fledged Windows 10 PC. It also comes with a fingerprint scanner, which supports Windows Hello, Microsoft's new biometric authentication system in Windows 10.

With PC hardware becoming smaller and smaller, new form factors such as the Compute Plug are becoming increasingly viable. Performance mightn't be overly amazing from these tiny PCs, but connected to a TV and you'll get the full power of Windows 10 from a device that can be easily hidden.
