Wrists aren't the only issue. I think split keyboards allow the hands to rest further apart which assists the shoulders and prevents too much internal rotation. FWIW, I'm a big fan of membrane keyboards now. The MS Sculpt is my current favorite, but mainly because I can't see spending hundreds more on a fancier keyboard that I can't try in person. It's not perfect, but it's a good value for me. IMHO, I think minimizing key travel is a good thing. Take a hint from musicians - unnecessary movement is generally bad.
