I wish there was an ergonomic/split version
I can't type on a horrible staggered keyboard anymore. Once you get used to it (about a week for me), it just feels so natural. I can never go back. Staggered keys are perverse, all the contortions necessary just to locate the keys with your fingers.
The only problem is that now I look like a total retard when trying to use anyone else's keyboard, which is a pretty regular occurrence unfortunately as I'm in IT.
I'm pretty sure the surface-mount parts are already done for you on the Infinity Ergodox, switches are just about the easiest things to solder because they're quite large and the pins are far apart.
So yeah, shouldn't be too hard, and you'll have a sense of achievement when it's done! I love using a keyboard that I've assembled myself.
