The Microsoft Natural 4000 keyboard has been designed to minimize the impact that long typing sessions have on your hands and minimize possible common workplace injuries. The Natural 4000 is part of the Ergonomics series and has been found to significantly reduce Carpal Tunnel Syndrome symptoms. The new Gull Wing design features a 14-degree gable, a natural arc and a curved key bed — bringing the keys closer to your fingers to reduce reach and unnecessary motion, while encouraging a more natural typing position. It also comes equipped with an optional palm lift for a seven-degree reverse slope and a cushioned wrist rest that encourages better arm and wrist alignment.

Assign your favorite document, page, folder, or image to anyone of the five My Favorites Keys for easy one-button access later. The Zoom Slider lets you easily zoom in/out of your documents, pages, or images, and is conveniently located at the center of the keyboard for ease of use. The forward and backward keys facilitate fast and easy web-page navigation and eliminate the need to move your hands from the keyboard while you do so. The Natural 4000 comes with a 7 mm tall soft-cushion wrist rest that offers better comfort and greater support while you work.

Take care of your hands and wrists, improve your endurance and comfort, and work smarter, not harder!

5 out of 5 eggsGreat if you have any wrist injuries.

Pros: Keys spaced well. Works with the new W10 KB/Mouse center. Lots of programing options.

Cons: Lettering on the keys starts to wear off in weeks, if you do not know how to type you will have to remember the KB layout. Cabled. No sleep/hibernate button.

Other Thoughts: This has been my favorite KB ever, still use it. Would love one in 2.4Ghz.

1 out of 5 eggsFails to work after bootup and letters wear off

Pros: Good ergonomic design that reduce strain on wrists.

Cons: Infuriating failure to work about 20% of the time after boot up. I must pull the USB cable out and reinsert it for keyboard to work.

Also, the key letters are rubbing off (on most commonly used letters).

I have the very latest software updates. I have reinstalled the entire software program and the problem has persisted for the two years I have had the keyboard. I have very little regard for anything sold with the Microsoft name.

4 out of 5 eggsExcellent keyboard

Pros: Excellent keyboard - very nice feel in the keys. The ergonomic split is absolutely fantastic, and I can hardly use a "normal" keyboard anymore as this is my home keyboard and I have a couple of Elite keyboards at work. The quality of this keyboard is overall good.

Cons: The letters are beginning to wear off in places (yes, yes - ASDW).

4 out of 5 eggsStill... My favorite keyboard ever

Pros: THE most comfortable keyboard I've ever used. The palm rest is soft, the curve puts your hands/wrists in a very comfortable position, and it just feels great. I really don't know what else to say.

Cons: I am on #3. The fact that I've been through three of these should tell you how comfortable the keyboard is.

The first one I purchased died after about a year. The z, x, period, and backslash keys would randomly stop working until they quit working completely.

The second one (The OEM I bought here at Newegg) had a similar problem after 13 months. The period key would only work if I put a good amount of pressure on it. Very annoying when I'm doing a research paper! I frequently had to back track and place a period.

Now I'm on number three. Just plugged it up.

Physically, I have no complaints on this keyboard except that the space bar is loud. Also, it seems that over the life of the keyboard, the keys will gradually get louder. Switching to this newest board, I've noticed that the keystrokes are a lot softer, and the space bar is really quiet. Expect the keys to become louder.

Other Thoughts: I wrote all that to get to this:
After my second keyboard was having the problem with the period key, I was a little frustrated. It was the OEM version I purchased here at Newegg, and apparently it has a one year warranty. I was only a couple weeks outside of the warranty period, so I took a chance and e-mailed Microsoft about the problem.

After a troubleshooting e-mail back to me, I responded and re-iterated that the keyboard worked great except I had to pound on the period key for it to work.

Much to my surprise, the next e-mail I received was an order for a brand new keyboard. They didn't ask for the old one back, and they didn't ask for the receipt. I was astounded at the support. Within a week of my first e-mail I had a brand new keyboard at my door.

In summary, I highly recommend this keyboard. For one, I think it's the most comfortable keyboard out there, and secondly, you'll receive great support if or when it fails.

5 out of 5 eggsGreat keyboard

Pros: Very comfortable, the keys on the keyboard are label in case you forget your bold, italic hotkeys, etc. Configuration options for the keys are MANY - command, launch program, web pages, etc. You can also alter the uses of the Web, Search and Mail buttons.

This keyboard slightly helps my posture and lately I've been feeling a little looser in the back of my shoulders - after a long day of working at tech support.

All keys are very quiet compared to previous major-computer-manufacture keyboard, that rhymes with Bell.

Cons: The favorite keys are nice, but do I really need five? How about a forward and back key for media player? (As opposed to (or in addition to) the foward and back key for web browsing.)

Volume key is cool, but it's pretty slow, has a couple seconds delay (on both PC's I have this keyboard on.)

Other Thoughts: Price went down since I bought it.

Serious techies who take pride in their equipment will appreciate this keyboard.

Forgot to mention the palm/wrist pad is soft, but durable. The F-Lock key is a cool feature, so you can use your F keys for different features without any ALT+ or CTRL+.

On a side note, if you plan to use the removable plastic height increaser (if that's a word) than don't plan on you keyboard fitting in your slide in/out tray - if that's how you use your desk.

1 out of 5 eggsPretty, but fatally flawed

Pros: The good sides of this keyboard are all the ones visible up front. It's handsome, it's an ergonomic design, and the key layout has been mucked with relatively little — most of the keys are where you expect to find them. There are a large number of extra keys, including four extra keys above the numeric keypad that probably 99.9% of users will never ever use, but at least they don't actually get in the way. The physical layout and shape is almost — but, sadly, not quite — as good as the late lamented Natural Keyboard Pro, which was possibly the best ergonomic conventional keyboard ever made. The cursor keys are in the expected inverted-T layout, not the hated diamond layout of the Natural Elite, and it doesn't feature the freakishly huge Enter key found on many keyboards (which usually displaces as many as three other keys into random and unpredictable locations). Key feel is generally good, without stick or bounce.

Unfortunately, these aren't enough to counter the 4000's flaws.

Cons: The problems begin with the F-lock. Yes, the keyboard will remember it's F-lock state ... usually. When it forgets, it defaults to the ALTERNATE state. But at least there's an indicator LED, so you have a clue what's happened when your F-keys just stop working one day. You can probably live with this; it's a minor annoyance.

More annoying, this keyboard has firmware glitches that cause it to occasionally start auto-repeating a key you didn't even press. So far, it's never been more than an annoyance, but having it auto-repeat the wrong key at the wrong moment could be catastrophic. It also frequently fails to register as a keyboard at boot time, causing even USB-keyboard-aware motherboards to complain that no keyboard is attached.

The greatest annoyance, though, is that within a few months of moderate use, the key caps begin to wear blank. This has happened on both of mine; I've never even owned another keyboard that's done this, and some of my keyboards are 14 years old.

Other Thoughts: My first Natural 4000 was replaced under warranty when the key caps wore blank. I'm guessing Microsoft replaced a LOT of these for blank key caps, and decided they were having to replace too many, but that actually fixing the problem would cost too much money; because — you'll love this — the official Microsoft position is now that the Natural Keyboard 4000's absurdly short key cap life is considered "normal wear". So, when your key caps wear blank in three to six months, you're out of luck. Unless you touch-type naturally enough that you never need to glance at your keyboard, go buy another keyboard.

So: glitches, functional annoyances, compatibility issues, poor build quality ... and worst of all, Microsoft will not stand behind the product they've put their name on. This is Microsoft's last failure for me. Once again, they are making their shoddy product my problem. I will never again buy another Microsoft keyboard. Microsoft has driven me to look elsewhere.

3 out of 5 eggsGood, but "wasd" gamers beware...

Pros: * Very comfortable handrest, useful utility keys (i.e. volume)

Cons: * Keyclicks are a little bit loud (same as the old MS ergonomic keyboard)
* If you use "wasd" to play video games do NOT buy this keyboard. The spacebar will not depress if you touch the left corner, which causes problems when your left hand is shifted all the way over.

5 out of 5 eggsGood buy

Pros: Very solid build and feel, can press 3+ keys with no error beeping unlike old MS Natural, very quiet, comfortable wrist wrest.

Cons: Keys are a bit soft, new curved design is a bit odd for me.

Other Thoughts: I had an older MS natural using ps/2 input for at least 10 years and loved it. But the keys were beginning to stick and a through cleaning didn't help so I came back to MS for my new keyboard and got the OEM version for cheap on Black Friday. Was a good buy. Unlike the old version this one seems to have no limit to the number of keys you can press at once which helps in gaming. The build is very solid feels like I could really cream someone's clock with it. Cord is longer than the old version.

The keys feel softer but it hasn't effected me much it's just a noticeable change. I've had no issue with the spacebar like some people are reporting. Most of the buttons are working fine under Win7 64 Home Premium with no software installed.

The split design is still very comfortable but the curve they added has thrown me quite a bit I'm still finding it hard to find my home keys even after almost two months of use. Still it's a great keyboard so far no major complaints.

4 out of 5 eggsOriginal DOA, Won't Regret Purchase

Pros: Great ergonomic design. Very comfortable. It is a very large, quiet, sturdy keyboard with a spacebar that is not the easiest to use only at first. Wrist cushion is not squishy, but supportive.

Cons: DOA, and had to pay for return shipping (it cost $8 for me in CA). So that's the DOA risk with these. Small 'Enter' and 'Shift' keys! Seems best for home use, not a workhorse on-the-job computer.

Other Thoughts: Check the space dimensions for where you plan to site this keyboard; it's larger than all my other keyboards.
