ErgoDox EZ vs TypeMatrix 2030

You can map any key to any position easily using a simple GUI, including making hardware key layers. And, since the firmware is open source, you can modify it to do anything you want. Many of the hardware components can also be altered/replaced by equivalent parts.

You can arrange each side of the keyboard to match your hand positions. Helps keep your body straight and improve your posture.

Because of its split design, the ErgoDox lets you optimize the positioning of its halves according to what's best for your body shape, even if you have broad shoulders and large hands.

The ErgoDox has an open design, so if you want to modify anything at all, you can fork the Github repository.

There are more keys which are easily accessible for touch typists than on common keyboards.

Unlike other keyboards, like the Lexmark M15 and Cherry G80-5000, where the only action performable by the thumbs is punching the spacebar, ErgoDox has extra keys placed near the spacebar, within thumb reach. This prevents the thumbs from being a bit redundant.

Almost all the keyboards have a small row offset (for example, on a standard QWERTY keyboard, the A key is not directly below the Q key. On the ErgoDox, this isn't the case: keys form straight columns. Together with the movability of the two parts you can stretch your fingers straight on, not slightly sidewards. This helps with touch typing, since you just need to stretch your fingers straight onward to reach the key above, rather than stretching it onwards and sideways.

Because of the nature of ErgoDox, within an open source community, there are advancements in firmware being made continuously.

With most programmable keyboards, you have to use their software in order to save and reuse your customizations. Using such keyboards on other systems "degrades" them to their default setting. Since with the ErgoDox the settings are saved directly on the keyboard, no matter the system where you're using it, your macros, tap dances and layers are always available.

The Ergodox doesn't allow you to reach over the centerline to hit T and H with a single finger, or whatever other bad habits you might have. The split design forces you to keep your hands in the right position.

The pre-assembled version offers an extensive 2-year warranty, provided you haven't taken it apart or physically broken it.

You can put the keyboards together, making it very easy to carry around.

The matrix layout reduces the travel distance of fingers. The keys feature membrane switches with double-scissor substrate, which are quite comfortable and very quiet.

This keyboard has a small footprint, only 324 by 133 mm. This not only leaves more room on the desk, but also and mainly reduces the lateral travel distance of the right hand to grab the mouse. It still offers a good numeric keypad thanks to the matrix layout.

Numerous skins are available, making it simple to keep the keyboard clean and even quieter. They also allow for multiple layouts.

This keyboard's matrix layout allows for increased typing accuracy. It gets rid of the typewriter keyboard legacy in favor of a more logical layout.

These layouts are not easy to find, especially the first one. While they don't necessarily increase the typing speed, they greatly reduce the travel distance of the fingers, and have a much better distribution of the keys than regular AZERTY or QWERTY layouts.
