This Microsoft Keyboard is great to work on fro long hours and its split middle gull-wing design provides me all the comfort that I need while I work on the computer. I just love the padded wrist pads and the zoom slider given in the middle of the keyboard.

Quality product
This is a good keyboard. As a retired ergonomic safety engineer, i have long enjoy the improved comfort levels the microsoft 'natural' keyboard helped to provide.

I like it
I have had one of these for several years. My wrists love it. The one thing i did was remove the caps-lock key. A editorial writer mentioned this in the paper, and it was like a light went on in my brain. I no longer screw up my typing thanks to this great idea. After 4 years of dropping it, and having my cat bat it off my desk when my back is turned, it is showing it's age, but i would buy another one. I just wish that they had one with the 10 key on the left side. I would as well like to have a dvorak setting and key covers, but you can't have everything.

Serious engineering flaw!
Let me preface by saying my keyboard says "v1.0" after the model number. I use mine at work so am on it all the time. I would prefer it to have not quite so pronounced a hump and angle, but that is just a personal preference and not anything to downgrade the stars on. The overall feel and appearance are nice with a good selection of extra function keys and a comfortable padding. If it weren't for the one major engineering flaw, it would be a good value. Here's the flaw - the heart of a keyboard is the keys obviously and the engineers dropped the ball on this one. First, the spring resistance is a little stiff in my opinion. However, the real problem is that they designed it so the keys must be pushed exactly in the center and directly down in order to work properly. Since no one can push every key exactly right every time, it results in a very unpleasant and error-filled experience. I did this experiment - you can do it too - just pick any key, and push it slightly off center with your index finger. It's like there's suddenly glue on the edges and it takes considerable force (for a keyboard key) to push down. Absolutely amazing that this would get by any design review! I don't recommend this keyboard unless they have fixed this flaw in later versions.
