What do you like about the corne ish zen?

It is an ortholinear keyboard, meaning the keys are arranged in straight columns not staggered like your current keyboard. I haven’t used ortholinear before, but I heard it takes time to learn how to type on it since the layout is different.

Do you like the ortholinear layout, split keyboard, ergonomics, mechanical switches, wireless/Bluetooth, all of it?

If you just want split keyboard with mechanical switches, the keychron Q11 is a nice choice, but it is not wireless.

If you want silent switch options, keychron also has silent switches you can buy. But you will have to install them yourself (it’s not hard).

Like others have said, keychron is a nice place to start. There are plenty of other companies.

If you want to look into ergonomic keyboards, there is also the ergomechkeyboards community on lemmy (not sure how to link)
