Summary: As with several other people who have shared their thoughts on this product, I must say that I absolutely hate it because of the tiny arrow, page up/down, home, insert, delete, and end keys. Pretty much the entire right section of the keyboard requires me to glance off the screen and look at the keyboard before typing.
Summary: I don't know what Microsoft did from their 1st generation of this keyboard to their latest, but they've totally destroyed whatever reputation their original natural keyboard had. I have both the old kind (arrow keys in an inverted-T shape) and a new kind (arrow keys in a cross pattern) This keyboard had inherent problems with Windows NT 4.0 (certain keys would not work properly) and the keyboard feels cheap.
Summary: My experience parallels a previous review. I also used the older Microsoft Natural keyboard (now the Natural Pro) and it relieved my persistent pain. When I accidentally killed my keyboard, I ordered the Elite model without thinking. Within a few days I was desperate enough to go back to a conventional keyboard. The arrangement of the Home/Page Up/Page Dn/End/Delete/Insert and arrow keys may allow the keyboard to fit in trays, but otherwise it is insane.
