Summary: MS has changed the construction of the keyboard. The space bar does not work when hit on the right side. It is a major PIA. Reading other reviews the same appears to be true of all natural type MS keyboards.
Summary: First off, let me say that this is a pretty solid keyboard. No complaints about the quality. However, be aware that Microsoft decided to rearrange several clusters of keys on this keyboard. The arrow keys are in a diamond pattern rather than the traditional (and IMHO efficient) "inverted-T". Also, the home/end/insert/del/pg up/pg down cluster has been dissected and rearranged, which causes me no end of grief and mis-keys.
Summary: 95% of this keyboard is of a fantastic ergonomic design. It's that last 5% that kills you. Specifically, the arrow keys. Granted, most people won't need them, but if you're a programmer, then having arrow keys chopped in half and shoved into a non-standard configuration is a major shortcoming. Even at a 49% discount, don't buy this keyboard. Buy an ergonomic keyboard with standard-sized and configured arrow keys. Trust me, you'll be happier for it.
Summary: I used an older Microsoft Natural keyboard for over five years, and it was excellent. By comparison, conventional keyboards are an occupational hazard. Unfortunately, I broke it while cleaning it, and I had to buy a new one. I picked up the Elite model without looking too closely ... but soon after I started using it, I was cursing under my breath ... because of the arrangement of the Home/Page Up/Page Dn/End/Delete/Insert and arrow keys.
