Re: Keyboard ecosystems
That doesn't apply to all keyboards. I like my Unicomp keyboards, and they're a decent evolution of the IBM Model M, but unfortunately not quite as maintainable. The casing can be unscrewed, and the keys individually cleaned, but the circuit board is almost impossible to disassemble.
After a drink accident it didn't survive, and I had to resort to the spare which I'd bought just in case. Hopefully I won't make the same mistake again; the keyboards are reasonably priced, but shipping from the US is a bit spendy.
