I'm upset that, despite the incredibly vibrant community around interesting mechanical keyboards (ergo or not), Jeff Atwood came to "save us" all from the shitty keyboards we weren't using, without taking 30 seconds to actually look around.
From coding horror:
I'm just happy to live in a world where the first truly great mechanical keyboard finally exists now, in exactly the form it needed to, with every detail just so, and I can type this very post on it.
To some of us, especially members of communities like GeekHack[1], that's a massive insult.

I had two MS Ergo 4000 in one year and both are damaged now. I have a cheap Amazon Basics keyboard for now.
Ergonomic keyboard users don't have enough alternatives. So we will complain until we get them.
I am happy with a split keyboard in two pieces and no numpad.
Strange. I've got one of these keyboards* and have had it so long the type has worn off the middle row. The nubs of the J and F keys had also worn down that much that I ended up getting an old soldering iron and scarring those two keys again.
Only maintenance I do is take it outside every now and again and blast it with the air compressor to clean it out (which is well past due).
* Actually I have a spare one in the cupboard for when my current one actually dies for good. I used it for about two days after I spilled something on the other keyboard and had to leave it out in the sun for a couple of days to make sure it dried out completely.
