5.0 out of 5 stars Excellent 8 Sep 2006
As a programmer, I type many hours every day and for a long time have been looking for ways to ease the stress my hands endure. At the moment, the available selection of ergonomic keyboards is very dire, but since buying this keyboard I can thankfully say this is not a problem.

Not all keyboards are created equal when it comes to ergonomics. One of the worst things about normal keyboards is their flatness. This keyboard and its predecessors have a raised middle which allows your hands to maintain a more natural angle. The gradient is slight but because human fingers are different lengths, it adds to the angle that your hands naturally form with the keyboard.

The left and right groups of alphanumeric keys are split and rotated slightly outwards. Here too the angle should not be too much because, as we have fingers of varying lengths, our hands do form a natural angle already. My experience of 3 models of Microsoft Natural keyboards has led me to believe that this angle is plenty and a greater angle would probably be too much. If you keep your keyboard relatively close, this angle will definitely improve things.

This keyboard has reverse tilt but you can remove the attachment and it does still have legs at the back. Having the attachment is nice because you can decide which tilt is right for you. If your desk is very low, reverse tilt might be suitable. I use my keyboard on my lap and for me, the best is without the attachment or legs. Many people talk about the ergo-benefit of reverse tilt, but I think it is contingent on your situation. Choose whatever feels right for you.

Hunt-and-peck typists will find this keyboard difficult to use. Trained QWERTY typists might also struggle initially.

5.0 out of 5 stars Very comfortable keyboard, but be aware of width 26 May 2006
Verified Purchase
This is the most comfortable keyboard that I have ever used. The reverse slope that makes it look so unusual is a wrist saver in itself. Combined with the split down the middle, different size keys, gentle touch (no clackity-clack), and the comfortable wrist support at the front, the whole package is a major improvement over any other keyboard that I have used (and I thought previous Microsoft natural keyboards were way better than most standard keyboards). Short of spending a lot for a "specialist" keyboard that pretty much moulds around your hands, I cannot imagine anything better than this for normal money.

The downside to watch out for is that if you are right-handed, your mouse will be pushed far to the right. If you have problems with your right shoulder/arm then this may be a problem. In that case you may find switching from a normal mouse to a 3M Optical USB Ergonomic Mouse may help up to a point, although you will still be stretching - you just won't be twisting your wrist to use the mouse. For me, losing the keys between the main keys and the numeric pad would make this keyboard perfect as that would make it narrower and avoid that stretch (in the process I'd move the PrtScn, ScrLk and Pause buttons to above the numeric pad, replacing the keys that are there now). Microsoft may want to consider that. But in the meantime, be aware of the stretch if you are right-handed.

Note added April 2009 - I have two of these keyboards, one at home and one that I took into work to use there. On both, one of the supporting "legs" at the back has broken. Each time this has happened, the keyboard had been in use for less than a year. Neither had been misused. It seems that the plastic used is simply not durable enough. I'm not reducing my 5 stars because of this, but I am disappointed that this has happened twice.

5.0 out of 5 stars Bleedin' marvelous 29 Dec 2006
I recently got this when I lost the spacebar from my standard keyboard (long story, lost it whilst cleaning it!!) and since I got this the list of benefits has kept on growing.

1) It is insanely comfortable to use, the reverse tilt stops you straining your wrists and the split keys keeps your wrists straight, not bent at an uncomfortable angle.

2) The keys are easy to press and responsive. Even the spacebar, which is the size of belgium, reponds to a press anywhere on it, even the very corners.

3) It enables you to press down lots of keys at once, up to about 10 at once (well, I ran out of fingers at 10!!)

4) The media buttons (or whatever they are called). All the customisable buttons along the top are very useful. They save an endless amount of time because instead of having to reach over to your mouse every time you want to open a new program, you can have 5 saved to the favourite buttons, open your email, search for a file, open your internet browser, even scroll up and down a page, for each of these you just need to move a finger rather than reach over to your mouse.

5) If you need to do calculations often there is a hyperlink button to open the calculator (just above the number pad) and they have some extra buttons built into the number pad that you often need to use, =, (, ), and backspace.

All in all, if you need to use a keyboard for any length of time then get this

5.0 out of 5 stars Different but good 6 Dec 2005
Before I start, I would like to point out that this review has been written on the first day of recieving the keyboard so consider it how you wish.
But saying that it should add a view from a different angle :)
As I said I recieved the keyboard today and it is my first ergonomic one, but so far I am enjoying it. Having typed on a standard keyboard daily for 15 years and this year getting a job involving using a computer most the day I am suffering some painful RSI. I decided to get an ergonomic keyboard and after reading the reviews here I decided to give this one a go. I also used lazy typing all my life so knew I would have to teach myself proper full fingered typing for this one.
So far I have found this keyboard quite an adjustment but already liking it. Still adjusting to the layout of the keys but my sitting position is straighter and far more comfortable.
My hands ached at first getting used to it, but progressive use and I'm getting faster and less ache in my hands.
I can see me sticking with this style of keyboard in the future, and it seems a good one too. If you want an ergonomic one from my days use I would recommend trying this.
