After years (and years) of rumors, it’s looking increasingly unlikely that you’ll ever be able to buy Microsoft’s dual-screen Courier device. There may be other companies that want to sell you something, however.Intel had a booth set up at this year’s installment of Computex and they were showing off more than just a processor with more than two dozen cores and its turbo-charged Optane SSDs. They also brought along an interesting little (8-inch) laptop.What makes it so interesting? As you can tell from Engadget’s photo, there’s no keyboard. It’s been replaced by a secondary touchscreen. This is a full-on E Ink display, not the kind of adaptive input surface that Lenovo built for its first Yoga Book.Intel’s prototype can effectively do the work of three different devices. Fold it open all the way and it’s either a full-color Windows tablet or a power-sipping e-reader. Set it up like a laptop and the E Ink display presents you with a full QWERTY keyboard (that could theoretically also switch to Colemak or other layouts).Both displays can handle stylus input, and there’s a dedicated inking area on the en E Ink side. Engadget’s Cherlynn Low reported that its ability to recognize handwriting isn’t perfect, but it’s good enough that she’d like to be able to buy one of Intel’s slick prototypes.It looks like she’ll be able to in the not-too-distant future. Maybe not directly from Intel, though it wouldn’t be shocking to see them launch something aimed at schools like the Classmate notebooks based on this design.At least two Intel partners are working on Lenovo’s second-gen Yoga Book has been upgraded with a full E Ink display and Asus was showing off something similar at Computex. They call their take Project Precog. Unlike the Intel and Lenovo machines, however, Asus opted for a pair of full-color touchscreen panels for its concept convertible.
