I am so glad these are back in stock. At $400 for a prebuilt, this is … well out of the price range of "buy one in case I need a backup for my existing, working keyboard" but if you're in the market for a split, staggered, programmable, low-profile mechanical keyboard, this is kinda the only game in town right now and as a user of its predecessor (the cepstrum) I recommend Keebio extremely highly

@glyph I must be just too old or something - I don't get the appeal of keyboards with no wristwrest. Some of those look pretty snazzy, but I'd like something more full-sized.

The Reverb Unibody, in particular, looks uncomfortable but also so pretty. A similar design with a wristwrest, function keys, etc. and I'd part with a stupid amount of money for it.

@jzb Different bodies require different accommodations. Personally I find that if I rely on a raised wrist rest, I smash my wrists into it and compress the tendons that way. However, I do want my wrists *to* rest, which is why a low-profile keyboard is so important to me: I want my wrists to be straight, resting on my desk pad. However, I don't want to lose muscle memory for when I have to use a laptop keyboard, which makes the typical setup for such a user (ortholinear) wrong for me.
@jzb This setup, and, I think, the one you want, are both exceptionally rare, but I do think the demand far outstrips the supply for this particular configuration, so I felt compelled to share the link to it for those few who might be waiting for such a product.

@glyph Oh, there definitely seems to be lots of demand. I hope it didn't sound like I was criticizing you for sharing; that was definitely not my intent.

Mostly I just feel like very few people seem to agree with me on what makes a good keyboard. Which is why I'm still sticking with ergonomic models made in the early 2000s....

@jzb what's your full set of criteria? given how much energy I have put into researching my tiny niche maybe I can recommend something
