The part about having to relearn how to type is not educated at all.
its just a different layout that almost never takes more than a day or two to get used to.
These keyboards aren’t meant for the average user. They are for those who would be typing a lot or otherwise just spending much time on a computer. It would only be the casual user who isn’t as technologically savvy as the rest of the world that would not find comfort in these keyboards.

And typing isnt like writing with a pen and pencil, there is no left handedness to typing at all.
To prefer to type with one hand again is speaking only of the casual user who apparently isnt doing work important enough for 2 hand use of a keyboard in the 1st place to these keyboards definitely are not for them. Typing is a two handed deal which makes for faster typing.

Bottom line these keyboards definitely are easier on the hands for those who actually would be using keyboards enough to notice a difference. I’ve been using ergo keyboards for years and i would never switch back.
