This is my biggest concern as well from trying one out, but apparently you get used to it. I currently use daily:

- a Microsoft Ergonomic Natural 4000 [1]

- A Kinesis Freestyle 2 [2]

- a Macbook Pro (2014)

That's a wide range of keyboard travels and force requirements, and I'm now comfortable with all. A friend got the new MBP and said he got used to its keyboard "within a day".

I have the baby Macbook 12" that I bought specifically for programming on the go. It took a bit to get used to, but now I love that keyboard.

I prefer shallow keyboards for coding -- large travel keys drive me crazy.
