I'm joining the choir here. Just no. I have no issues with reduced size keyboards, I have
two four(just looked). But there is a limit to how many keys that can be removed and remain reasonably functional.
@ Epomaker
It doesn't matter how popular you claim the above reviewed keyboard is, it is niche to an extreme and will never be anything more.
Instead of reducing the number of keys, try taking a full function keyboard or something close and reduce it's physical size/scale. You need to experiment to find out how small is too small to be useful and comfortable, but it's far better direction to go.
For example: Try something like the following and scaling it down 30%;
This keyboard is a an 80% model that has all of the functionality I require. It could be smaller though.
(In case anyone is wondering, that example can be found
here.)
