I find it difficult to stay on 60%.
I have been a strong advocate of 60%, but with much more experience now I think I was wrong.
I have really tried to keep the 60% form factor, even designing special layouts to deal with them (SpaceFN and GuiFN), writing code to implement these layouts (in Karabiner and TMK firmware) and ordering matching keycaps from WASD.com

https://geekhack.org/index.php?topic=57723.0After months and months of use, my opinion is that the 60% form factor (Poker, HHKB, ...) may be suitable for
some, but it cannot be recommended in general.
The deal breaker is the lack of arrows. I know it sound obvious, and I'm already hearing the objections.
Naturally on a 60% you have the arrows, but they are on a second layer: you press an "Fn" key and some other key in order to get an arrow or any navigation function. You end up spending all your time pressing on the Fn key.
The problem, and many people don't realize it, is that the arrows are among the most used keys on a keyboard.
I didn't realize myself how much used they are, but I have since installed a keyboard stats utility on my main computer, and the numbers are telling:
When I press a key:
- I use space 10.9% of the time (it's the most used single key)
- I use "E" (the most used letter in many languages) 5.8% of the time
- I use an arrow 22.4% of the time!!!
It should be obvious that it is a serious ergonomic handicap to not have direct access to the arrows.
For this reason, I have now stopped investing in 60% keyboards, and I limit myself to keyboards that are as close as possible to the 60% form factor, but which still have arrow keys.
For example:
- The FC660C or FC660M
- The Matias Laptop Pro (which also has the advantage of being Bluetooth)
