2 out of 5 eggsCan't do it.

Pros: It cost $40.

Cons: It's not worth $40. It's not worth $5. To me, anyway.

It's not my Comfort Curve 2000 -- The best keyboard ever made. They didn't last forever, but they didn't cost much, so I didn't mind replacing them.....UNTIL MICROSOFT DISCONTINUED THEM!! Did you know people selling out their stock of those can charge $150 or more for what used to be a $19 keyboard??

Other Thoughts: I wanted to see if I could get used to the split keyboard. Nope. To make matters worse, the direction of the keys' stroke doesn't line up with the direction my fingers press.

My 2 eggs isn't to say this is a lousy product. As best I can tell, it's well made, and I'm sure some folks love it. No, the 2 eggs is because this layout isn't for me, and for Microsoft discontinuing my keyboard without a good substitute.

1 out of 5 eggsBig time sink, total loss

Pros: Seems solidly built
Works fine until Win7 loads

Cons: Could not get it to work with my Win7

Other Thoughts: There is no way I'd recommend this to someone using Win7. The keyboard obviously works ... it's fine until the Win7 drivers load, and then it no longer works. I can inspect the device in Device Manager, where it shows up under the Other category. I have tried downloading and installing the Microsoft drivers, and have followed every other bit of web advice I could find. No luck. This keyboard is apparently much more than a PS2 emulation, and therefore *needs* a special driver? I don't know. Win7 couldn't find the driver for it either, even by checking Microsoft's online driver database. I have to give up ... 3 hours spent on a $30 keyboard is an obvious loser.

5 out of 5 eggsMuch Better!

Pros: - Switching to this keyboard made my bible bump shrink substantially!
- The keys are way easier to press than the used Natural Ergonomic Keyboard 4000 I snagged from the Admissions department. There's less hair and flakes, and the keys are like butter!
- It allows me to sit closer to the monitor, as my arms don't have to be crunched in front of my body to type.

Cons: - None that come to mind.

Other Thoughts: I would recommend this keyboard to everyone! Sure, it takes a little bit to get used to, but you'll be glad you did. Your wrists will thank you, your shoulders will thank you, and your mood will thank you! Do it! Put one of these babies in your shopping cart and check out!

3 out of 5 eggsMediocre

Pros: It's has all of the keys

Cons: I've been using MS Natural keyboards for 10+ years due to RSI problems. This one is not my most favorite keyboard, I like the older beige natural keyboards a lot better. Feels a bit like typing on a sponge, requiring too much pressure since my fingers don't know when a key is fully pressed. So that feedback is lacking.

5 out of 5 eggsNice Keyboard

Pros: looks, price

Cons: nothing really other than the spacebar seemed hard to press at first.

Other Thoughts: I've owned this keyboard for a few months and although it took a few days to get used to, I absolutely love it. I'm a software developer so I spend countless hours at a computer and this keyboard has definitely helped with my carpel tunnel. The only bad thing is that I can't type on a traditional keyboard anymore.

3 out of 5 eggsweak offering

Pros: my large hands love the split keyboard with raised center.

Cons: the letters are painted on and not incised into the keys, as was true of the previous model. The letters began to wear off within just a few months and now, 2 years later, the ones used most often are completely blank. This is tolerable if you're a touch typist, which my grandkids are not.

Other Thoughts: overpriced for what you get

5 out of 5 eggsGreat Keyboard

Pros: Very easy to use. I have had three keyboards in my life, and this one is by far my favorite. the features are great, and easy to use.

Cons: The space bar is more difficult to press due to the natural curvature of the keyboard, but not by much. It bothered me at first, but i have grown used to needing to press it harder than the rest of the keys.
