I’m typing this on the world’s largest keyboard, a 178-key best designed to make you more productive

Chyrosran did a video review of this thing a few months back. He's a big fan of large keyboards with lots of macro keys so no surprise he's been on top of this keyboard. Definitely not my thing but it is still cool.

I would point out that while their classic layout is very much symmetrical, it accomplishes this by uses a non-standard 0.5u offset between all rows. The modern layout that matches the standard row offsets that normal keyboards use is not symmetrical and is offset to the left with the right hand having one more column then the left hand. Most ortholinear and ergonomic keyboards are symmetrical such as Planck/Preonic, Ergodox, Kinesis Advantage, etc...
 
It could use a clock, and maybe a CPU monitor.
Might as well throw in a dozen streamdeck/loupedeck style keys too, while they're at it. And a couple of those spinny wheel things, even though I don't know what they're for. Really it's a pretty incomplete keyboard, if you think about it.
 
A keyboard has to have a numpad detached (or mounted, for example, over the main section), otherwise sooner or later it ends up with back pain and the productivity goes kaboom. Unless, of course, you don't use your mouse much.
 
We laugh at your puny keyboard:

But seriously, the Hyper7 R4 is really great; don't think I've seen a new keyboard that I've liked more.
 
Thanks for the review! Now do the Keymacs... which is even more like the Space Cadet since it imitates the actual Symbolics keyboard!
