Yeah, I have that keyboard at work and its spot on for me, but non touch typists find it freaky and at home other people use the pc as well as me. The curve is less intimidating than the split keyboard.

@everyone

My supplier gave me a number for logitech support so I called them. They said the keyboard is driverless, then suggested I install some drivers. I did this but no difference. Then they said sorry they have no further suggestions thankyou for calling logitech today.

Meantime I tried out the keyboard on another pc (which also runs XP) and it worked, with no driver installation. I put my old keyboard back on mine, its working and my wrists hurt again when I type any significant amount. Since I write short stories this is an issue, and I'm back to square one.
