Such devices already exist and they running on Chrome OS. There is Lenovo Duet and a hybrid from HP. I had Lenovo device in the past and it was solid, well designed piece of kit for a fraction of the price ( comparing to an iPad). In the UK you could get it for £349 with the keyboard and stand case included in the box. There is also support for Pen/stylus although have to be purchased separately.
I don’t think this kind of device is about standing out from the crowed it’s about complementing existing ecosystem of devices. Like an iPad does not stand out, it’s a slab with big screen but it gets the job done and it gets it well. Also plethora of peripherals available for these devices adding more functionalities is a class in itself. Hybrid device appeal mostly to students, writers, researchers or journalists so I don’t think it needs anything glyph related, although backlit keyboard would be advantageous and if Nothing could implement glyph into it, that would be something to talk about.
