That keyboard looks pretty bad. They could've rearranged the controls to utilize the entire width for the keyboard, like the GPD Win (2), to at least make the keyboard bigger and positioned better for ease of use. Having to reach across with your thumbs to the center of the device is not ideal and seems like it would get very uncomfortable if you try to type anything more than a few words. The keyboard seems like an afterthought on this one, like they hadn't even come up with the idea until they were 75% done with the design process.
And I don't understand why the secondary screen is so small. There is so much empty space around it, it looks weird. Maybe they just couldn't find an off the shelf screen with the specs they wanted that was just the right size, though that seems unlikely.
I'm glad to have more competition in this form factor, as I do like the clamshell design and personally think it's really cool that these things are essentially miniature laptops, but GPD did it better 7 years ago with the GPD Win. Aya Neo's other devices are cool and sleek but they clearly have some catch up to play when it comes to clamshell devices.
I still have an OpenPandora sitting around somewhere from way back, that thing had more or less the same layout as the GPD Win (2) and the keyboard was actually quite usable, I used it to chat with friends on the go (as this was before smartphones)
That came out around 13 years ago and I'd say even back then they had nearly perfected the layout and functionality of a handheld, clamshell pocket computer, even if the design looked dated. Aya Neo should just copy that layout and they would have a much better device.
