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.
Summary: Office Keyboard è uno dei più recenti prodotti di casa Microsoft, leader nell’ambito della produzione di software, ma sempre più presente nel campo hardware, soprattutto con lo sviluppo di strumenti per la comunicazione uomo-computer. Si tratta di un prodotto che è figlio di una tendenza che spinge le grandi case produttrici a creare strumentii appositamente studiati per l’utilizzo in simbiosi con applicazioni particolari.
