In my case, I started out with the classic typewriter layout, by sticking labels on the keys. It was a mess, and couldn't be done at work.
I have since taken a more pragmatic approach and moved to phonetic.
For starters, I'm not even sure the traditional layout is scientific.
But more importantly, while it may work for large languages with ready made keyboards, insisting on solutions that most people will not do, would actually be hurting the language in the current digital age.
