I swear by my natural pro. Once you use one, everything else seems, "uncivilized". They also look damned good too, gets you in with the ladies😉. In the case of my MS natural pro, I think it has the best feeling "key push" of any other KB i have used(actually the IBM ones are really nice). If you can get one for a good price go for it, I have had mine for a little over a year, and will never go back.
Oh yeah, I can type faster with it too, it also encourages better typing, since it is harder for one hand to reach to the other "chunk".
Peace😎
