Query: Anti-ergonomic for me

Microsoft Natural keyboards have been kicking around for a long time, and while they are reasonably inexpensive and decently constructed, I find them even less comfortable to use than flat keyboards. The only keyboard I have ever found to be a real improvement on standard ones is the oddly shapedKinesis Advantage USB - Keyboard - USB - black. I have used mine (an older version, of course) for over ten years, despite its worthless function keys, because it is the only keyboard I can find that lets me type as much as I want without causing my wrists to hurt. My hands are large with long fingers, but otherwise normal, so I don't know why my experience with ergonomic keyboards seems to be atypical.
