Most reduced ergo keyboards are heavily reliant upon layers to provide access to function keys, media keys, numpad, etc. I have several ergo keyboards, and my favorite (and one I'm currently typing on) is the Atreus [1]. In the default configuration it's one press with the thumb to access the numpad without moving the hand [2], and another keypress puts the function keys there instead (with the same layout for 1-9) [3]. This is all customizable of course.
It definitely takes some getting used to, but once you do it's such an efficient and enjoyable typing experience.

keyboard.io also recently completed a kickstarter campaign for mass-produced Atreuses and are taking pre-orders for the next run: https://shop.keyboard.io/products/keyboardio-atreus

Also using a HHKB Pro 2, without prints. Best keyboard I ever had.
My alternative would be Atreus, but I am not that into building keyboards.

I love Dvorak and I love my Atreus in Dvorak-mode. https://atreus.technomancy.us/

I've had a few different ergonomic/ortholinear keyboards and I really, really highly recommend checking out the Atreus keyboard if you want to never look down. It's so ridiculously small (42 keys, no number row) that you know exactly where your fingers are the entire time you're typing.
It has programmable layouts/layers but if you just stick with the defaults it's no more context-switching than modal editing. QWERTY is the base layer, next layer up does symbols, arrow keys, page up/down, and a numpad. Then on the third layer you have function keys and a few extras (e.g. insert, volume up/down). Took me a week or two to get comfortable with the first two layers, another few weeks before I felt confident with the third, and maybe 6 months in now I can't imagine ever going back to a regular keyboard.
Typing `*{@` is as easy as typing `prw` with one (thumb operated) modifier held down.

I've been getting into electronics lately and really loving it! My inspiration was my new Atreus keyboard[1] (first one ever sold!) and the epiphany while playing Minecraft that making your own (useful) stuff is tons of fun and super rewarding. And it doesn't have to be computer programming anymore!
So I booked it to Radio Shack and bought the Make: Electronics book and the accompanying kit. (I could have scoured for the individual parts, this book lists them and recommends it, but it was a nice convenience to have a pre-made kit by the same company, and presumably the same author.) And so far I've only learned about resistors, capacitors, and other basic circuitry, and it's a bit math-heavy, but it's really exciting!
I also have a serious electronics project in mind that acts as really good useful motivation. It's a toy that's probably relevant to HN, and if I ever accomplish it, I plan to share it here.
Hobbyist electronics is really fun, and so far I recommend it! (That said, I have no ambitions about inventing the next great CPU or memory chip -- you probably need decades of college-level education and experience on this to be able to innovate at any serious level these days.)

I feel this quite a bit. When I was young, I had a ton of time and no money to acquire the needed equipment. Now, I finally have the money to get basically whatever I need within reason, but no time to use it.
I am typically able to resist the urge to succumb to GAS, but I don't always. I still have an incomplete atreus (http://atreus.technomancy.us/) in my basement; I set it aside when I bought a house, and haven't had time to revisit it since.

> I don't know, but I still like the idea behind the "netbook": small, portable form factor with real keyboard, cheap machine, decent battery life, GNU/Linux.
You and I clearly have very different definitions of "real keyboard".
I've actually been wanting an Android tablet that I can connect a USB mechanical keyboard to (probably an Atreus[0]) as a Chromebook replacement. Problem is, I want vanilla Android (no bloat), and for it to get updates for at least 3 years.

That's really cool. Was looking at the Atreus[0] and Ergodox Ez[1] before, but this one looks even better.

If you're looking for a mechanical ergonomic keyboard that you can also easily take with you, I suggest taking a look at Atreus[0], a 42-key column-staggered keyboard.
I got one a while back. Haven't gotten around to publishing my build log, but building the keyboard was a lot of fun.
With the somewhat steep learning curve out of the way, I've been really enjoying it and gone are the days of wrist pain.
Oh, and I'm in no way affiliated with Phil or the project, just a very happy user dropping his 2¢ here.

Built my own (from a kit), the Atreus: http://atreus.technomancy.us/
I like that it's small and portable and has forced me to learn to type with all 10 fingers rather than doing rapid-fire with indexes and middles on a regular layout.
I've also used the TEK, which was equally awesome, just bigger.

> Any chance you could provide a picture of it or a link to something similar?
Sure thing; I have photos and kits for sale at http://atreus.technomancy.us
It takes a long time to learn since it's a pretty big divergence from the conventional design. It only has 42 keys, but with the fn layer (activated with the thumb rather than an awkward pinky reach you normally see on laptops) you can still hit all the keys you need. The other upside is apart from being much smaller it also means your fingers never have very far to reach, so it's also more comfortable.

I'm typing on a TECK right now, and I've been doing so for over a year. I still hate it.
I use the Workman layout, and I like the layout... BUT THE CHATTER!!!
At first I had to get used to the layout, then supposedly wait for the keys to "break in", then clean the switches.
It's not so bad... just annoying enough to barely not buy another keyboard. It was only last week that I ordered http://atreus.technomancy.us
If that one has chatter too, I don't know what I'll do. Go back to rubber dome maybe. Despite all the bad things people say about them, my old kb never missed a single press.

you can grab a full kit here: http://atreus.technomancy.us/
but it's pretty easy to source the parts, see https://github.com/technomancy/atreus/ (which also has links to build instructions)

You appear to think that mechanical boards cannot be ergonomic. I agree that the Model M and friends are terrible, but that's hardly[1] the end[2] of the mechanical[3] ergo[4] story[5].
