I made a gallery of split keyboards a while ago: https://aposymbiont.github.io/split-keyboards/

It is missing some newer designs, but it at least shows that not all split keyboards are tiny things with half the keys removed.

I've been using an ErgoDash for 6 years. I have one at home and another at work. If there had been a similar keyboard with real F-keys in 2019 I would have chosen that instead, but it's only a very minor annoyance.

If I was looking now I think I'd buy the Kinesis Advantage360 (I could keep using the layout I am now used to) or Kinesis Advantage2 (dished, but has fewer keys than I'm used to).

(If anyone keeps up-to-date with split keyboards etc and wants to take over the gallery site, just let me know. I'm happy with the keyboard I have, so I don't spend time researching more.)
