Open-source split keyboard based on the Kinesis Advantage's layout.
Ranked in these QuestionsQuestion Ranking
Pro The ultimate in customisability
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.
Pro Split design lets you optimise positioning
You can arrange each side of the keyboard to match your hand positions. Helps keep your body straight and your posture better.
Pro More roles for the thumb
Unlike Lexmark M15 and Cherry G80-5000 whereby the only role ideally suited to the thumbs were spacebars alone. ErgoDox like a fair few other split mechanical keyboards have extra keys placed near the spacebar but within reach of the thumb. This prevents the thumbs from being a bit redundant.
Pro Open source
The ErgoDox has an open design, so if you want to modify anything at all you can fork the Github repository.
Pro Firmware updates
Because the nature of ErgoDox is within an open source community there are advancements in firmware being made to this day.
Pro Comfortable for those with broad shoulders + large hands
Because split design lets you optimise the positioning.
Pro Many accessible keys
There are more keys which are easily accessible for touch typists than on the usual keyboards.
Con Needs to be assembled
This can be fun, but some just want a working keyboard without having to spend three hours with a soldering iron. It's tricky to find pre-assembled ErgoDoxes, and they're not mass-produced.
It is also possible to commission an enthusiast for instance to build one up as well. Some massdrops of the ErgoDox kit did came with an option allowing one to choose whether to have it pre-made or not.
Con Tends to move around during use
Con Difficult to source
You have to either source the individual components and build it yourself or wait for a mass drop group purchase.
UPD: Check comments below
Con Hard to use with smaller hands
Con Can't return it if you don't like it
As the Ergodox is an open sourced design and you're likely to purchase it from Massdrop it's not possible to return the keyboard if you don't like it.
