Intel revealed its new Star Brook prototype laptop at last week's IDF 2015 conference in Shenzhen, China. This Skylake-based system has a 12.5" screen with 2560 x 1440 pixel resolution, it's just 20mm thick and weighs under 1kg.
One of the interesting things about Star Brook is that Intel follows in the footsteps of Apple's most recent MacBook by getting rid of the dedicated power port. The prototype from Intel is charged via a USB 3.1 Type-C connector, this new protocol can drive 20A at 5V. That makes 100W which is more than enough considering most laptops come with a 65W power adapter.
The Star Brook prototype comes with two USB 3.1 ports so you can still connect one other device without the need for a hub.
