Summary: I've been in the computer industry for over 25+ years and I started using THIS version Microsoft ergonomic keyboard over ten years ago. Most people hate them at first: BUT, if you stick with it and us proper typing methods you'll double or tripple your typing speed. VERY, very heavy duty built.
Summary: Yes there is a learning curve. Yes it takes desk space. Yes it looks weird but after using this flavor MS keyboard honestly you can't live without it. When I go to user's desks and they have an old-school rectangle board I cringe. I have used this model of keyboard for 11-12 years.
Summary: i have been using this keyboard for 10 years, my old one broke and i wanted the same exact model the one that i got to replace my old one came and was slightly smaller and made of a lower grade plastic so, overall i still want this type of keyboard because it is supposed to prevent carpal tunnel but...
Summary: In combination with a good ergonomic mouse (I use a thumb style), this ergonomic keyboard has salvaged my career as a workaholic. I love my work and never run out of things to write about; but after a few decades of heavy usage, my wrists and fingers were showing all the classic early warning signs...
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: I work in IT, so I get to try A LOT of different keyboards. This is, by far, the best keyboard that I have ever had. I got my first Microsoft Natural Elite about 10 years ago and am only now replacing it because I took it apart to clean it and lost the screws. These things last and last.
Summary: If you aren't used to the split keyboard then it may take some time to adjust. Capitalizing the "b" key is troublesome, but that can easily be accomplished once one gets used to pressing the right shift key to do so.
Summary: Over 10 years ago, I purchased this same keyboard to write my dissertation and I can't live without it. I had to replace that board recently and I purchased two (one for home and office.) I can't type fast on any other keyboard. I will never be without one as long as they make them.
Summary: I was concerned this would not work with a Mac because all the literature - on the web and on the box - mentioned only PC system requirements. Plugged it into the Mac and I was back in business.
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.
