Toshiba has announced what it calls the world's first 12.5" convertible with a 4K screen. The Satellite Radius 12 is a svelte machine with a 12.5" 3840x2160 IPS screen. This panel can reproduce 100% of the Adobe RGB color gamut, which could make this Satellite a good choice for color-critical work.
The display's color accuracy is certified by Technicolor, and its surface is protected by Gorilla Glass NBT, which should add a certain measure of protection against scratches and drops. The 360º hinge lets the screen rotate freely, allowing the laptop to be used in a total of five modes.
Toshiba says the Radius 12's innards are built around Intel's Skylake CPUs, and the company claims it's one of the first machines to support Windows Hello facial recognition, powered by an infrared camera. We can also spot what appears to be a USB 3.0 Type-C port. The chassis is a mere 0.6" (15 mm) thick, and the whole system weighs in at 2.9 lbs (1.3 kg).
The Satellite Radius 12 will be available in Q4 2015, though there's no word on pricing.
