I had the same experience, but with a preonic. It's not that hard for me to use a regular keyboard but it definitely feels akward and when I do I type slower and more prone to errors.
Yeah I've been thinking about getting a preonic, or at least something slightly larger than the planck, at times I find it a bit too minimal, also I would like to have two orthos so I don't have to lug one to work every day.
