Summary: I have bought a number of these keyboards - I really like the ergonomic feel of them. My wrists feel much better using this keyboard. The downside is that they don't seem to last as long as regular keyboards.
Summary: Basic keyboard, works great, hasnt broke.
Pros: Long lasting, Ive used this keyboard for quite a few years now.Keys are starting to get a little dirty, but not bad. I like the shape and of the keyboard, not sure how much it really helps me ergonomically.
Cons: If you get use to this keyboard at home, you might have to buy a second one for work.
Summary: FYI: this is a PS/2 keyboard, with a USB-PS/2 adapter. They keyboard, as far as I can tell, is identical to the original Microsoft Natural Keyboard Elite model KB-0045. The only difference is they added an adapter, in the form of a 4 inch cable extension. This is *NOT* is USB keyboard with a PS/2-USB adapter.
Summary: Overstock has a misleading picture of this item, showing it in black. It is in fact white, as I discovered when mine arrived. It does say white in the item description, but I thought I could trust the picture. My mistake I suppose. Otherwise a good item and fair price.
