Hmm
Reminds me of a time when tablets first became an option for business use.
Our senior people demanded them, it was imperative they were seen walking around with the lastest device tucked under their arm (I think they were Dell Venue 11s).
Then they said , "they're hard to type on we need a keyboard", So they got a magnetically attached (expensive) keyboard to go with the (expensive) tablet.
They they said, "it's hard to select things, we need a mouse". So they got a bluetooth mouse to go with the keyboard and tablet.
When it was pointed out that they had effectively built an expensive but underpowered laptop piece by piece and they might be better off with a laptop; this was dismissed out of hand, they needed a tablet because the little people used laptops.
I'll add, all along while this was happending they also kept their full desktop systems so they were running double licences for everything.
This seems like that, everything in a keyboardmkaijng it easily damaged expensive and contrained. For a desktop you'd be better/cheaper with a SFF PC and cheap disposable keyboard to cope with inevitable coke/coffee spill or just having some heavy books dumped on it. If you need portable a laptop would still work better. If you want a portable computer to plug in and run a console it'll be cheaper to use a RaspPi device.
So I'm struggling to see the niche for this?
