My strategy was to make a mental note of where my fingers expected the key to be and then map them to a layer later. That was I wasn’t working against already engrained muscle memory. It helps to have layer themes too. I have alpha, numbers, and coding symbols.
I have it on both and they’re pretty much identical. Having buttons available can be sorta nice for specific actions, but on the other hand a phone is easier to carry around. Both are great with minor pros and cons.
