It's always interesting how different what is comfortable can be from one person to the next. I can't type performantly on non-ergonomic non-split non-tilted keyboards any longer, after ~20 years of typing on split ergo keyboards. The way that straight keyboards orient my wrists causes discomfort within an hour or two of use. In my case the Microsoft battleship keyboard, the 4000, is the only thing I find comfortable. I can type on it all day with zero stress on my wrists or hands. Anything else and I suffer noticeable hand & wrist stress after a full day of work. The base of my hand / wrist area also likes the subtle padding on the 4000, it's just enough to provide some additional comfort without being annoying.
