For the past month or so, I've been using a split ergonomic computer keyboard, specifically this one:
For the nerds, it's a redox rev1 that I built myself with a 3d printed case and outemu blue switches.1 I apologise for the complete lack of build logs, I'll post them for my next build.
This keyboard is not only a split keyboard but also ortholinear - the letters are arranged in straight vertical lines instead of being staggered like a normal keyboard. This makes touch-typing more logical and easier and is claimed to reduce RSI, and I personally quite like it.
Getting used to this keyboard has taken a while. For the first few days I could barely type, but within a week I was able to use my computer fine without a backup keyboard and by now (almost a month later) I feel like I can type quite confidently. Not bad for somebody who couldn't touch-type at all when I started, and on blank caps. I find the split makes the keyboard more comfortable and less cramped feeling than a normal keyboard, and the ortholinear layout is a lot nicer and makes a lot more sense. After using this keyboard for a while I wonder how anybody still uses a normal one. It's just better.
The bolts in the picture are a solution for tenting - raising the keyboard up in the middle. This is good for ergonomics as it keeps your arms in a more neutral position. I personally do not use the tenting most of the time, keeping the keyboard flat (which is worse for ergonomics, but makes typing a lot more stable).
One of the main draws of ergonomic keyboards for a lot of people is reducing wrist pain. For me personally this seems to have made no difference whatsoever.
So overall? Pretty cool. Yes, this post is badly written. Sue me.
Yes, I know they suck, it was a bad decision for this build, doesn't change any of the rest of the post.
