I'm still trying to find a keyboard for older, arthritic, dyslexic fingers. I'm currently using an older MS split "ergo" board. Love the keys with the tactile feedback they have, and the full-size, but not loving the split design, nor the "ergo" wave. Some of the keys--ENTER, BACKSPACE in particular, are too narrow compared to the keyboards I'm used to.
Just tried out an HP board that was NOS surplus from the office. See post above. Keys too small, entire board too small, no tactile feedback from the very light keys, etc. It's gone on to old electronics hell now.
I guess I'll look at more offerings from MS as the keys are really nice, but, once again, suggestions are appreciated. Being way out here in the boonies means there are no B&S stores (some BS stores, 'though) to try things out. Ordering and rejecting gets old.
