I’ll try to be a bit more critical, because points made in comments so far have been mostly positive.
Don’t get me wrong, I love the keyboardio 95% of the time, but it is not perfect for me and I have noticed some annoyances over the course of a year with it:
After comparing it with a few other keyboards that have different switches the keyboardio feels pretty bad. It seems to be that Matias switches bind a lot when the pressure on the key is off center. That in combination with the keycap design (some keybio keys have off center stem placement) make it worse than just pressing the switch on its own. They are also sensitive to dust and dirt accumulating, which means you’ll have to clean it out every once in a while. The clicky variant makes the issue way more noticable. On the quiet click it is still there but one can live with it and it never stands out a lot, it just adds a slightly cheapish general feel.
A thing with using split keyboards - When you need a mouse often and you have the keyboard positioned perfectly at the width of your shoulders to have the ergonomic typing, it is going to be fatiguing and/or uncomfortable, no matter where you place the mouse. The keybio occupies a lot of desk space in general and the space between mouse and keys is increased a bit due to the octopus stand and the wooden body. So when you have to move your hand over, you have to place the mouse farther to use it comfortably without bumping into the keyboard, which in turn is a uncomfortable movement to make over and over.
Gaming sucks. Especially because most games heavily rely on the mouse. There is nothing wrong with the keyboard inherently, just the experience. Since the keyboard is split, reaching for the other half is no fun, so you have to put all keybinding on one half, which is already impossible with some games. After remapping my 17th game and printing out an overview of the mapping for each one of them because I have learned the default one over the years and couldn’t manage to learn my keybio bastardised layout for each one during my casual sessions, I just gave up and bought a Steelseries Apex Pro TKL exclusively for gaming.
If you don’t type a lot, you probably won’t notice much of an ergonomic difference compared to a regular old keyboard.
I’ve picked my desk and chair so that I can sit for hours without any back or shoulder pain, the only kind of pain I have is in my wrists, but keyboardio doesn’t have enough of a sideways tilt to help with that.
While coding I type in short bursts and not continuously, with lots of autocompletion and many key combinations for my IDE. Due to the lack of dedicated F keys, some of them are hella awkward and require finger acrobatics, which are not good for finger pain/fatigue. Others are impossible to do one handedly at all so you either have to let go of the mouse or you are back at the gaming problem of remapping. I’d prefer to have more keys, if not dedicated macro keys then at least the F ones.
I would guess I type at most for 1h total during a day of work, with around 50wpm, so personally there is not much difference in speed or body feel after a day of work compared to when I’m not home and doing work on my laptop.
Your experience with that might be very different though, it heavily depends on your body, your habits and what kind of typing you are going to do - the more you type the greater is the benefit of a keyboard that is ergonomic for your body.
It reminds me of linux, because it works on the principle of “you reap what you sow”.
Out of the box, it will probably not suit you very well in many aspects and you’ll have to put in time and work to make it more tailored for you. Some people would rather just buy a keyboard and use it. If you are a windows user … maybe its not for you.
Now that I have it, it is very nice to have and as a side effect it has taught me many things about ergonomy, how keyboards function and how to touchtype. But if I had the option to try one for a month before buying, I would have probably held back on the purchase. A lot of people resell theirs after a few weeks or months, because nobody told them clearly how and why the keyboardio might not work out for them.
Two alternative keyboards that I can recommend checking out are the kinesis advantage 2 and the ultimate hacking keyboard. One of those might work better for you, but they are not perfect for me either.
Otherwise the keyboardio definitely feels like a superb typing device for when you want to actually type (and not use shortcut combinations or the mouse) It is immediately noticable how much work went into designing and perfecting the layout. It traces my fingers natural motion very nicely.
Personally I find it very fun and satisfying to use, but the flaws I mentioned above make me want to get a better alternative, as soon as one gets created, or at least take a few months of my life to heavily modify this one in hardware and software, which I havent done at all by the way. I prefer to just use things, so I’ve kept with the default US layout, even though I’m from Europe.
If you don’t mind the flaws that I listed, the keyboardio is totally worth it. This is a very consumerfriendly product - it is made to be tinkered with and thus uses widely available standards for the coupling cable, the stand mounts and even the mcu. The customer support is amazing and I truly feel like the people behind it care about you and your typing experience.
