This keyboard is awesome for those with wrist pains. Since I've started using it (~2 months), the pain in my wrists have gone away when typing. When I have to use a regular keyboard, my wrists start to hurt again after any non-trivial amount of typing. The curved layout fits almost perfectly into my hands. I have regular sized hands and I have trouble reaching some of the more distant keys. I would not recommend this to anyone with smaller than normal hands.
The built in 'zoom' functionality between the split keys is quite ingenious. Now, when I read webpages, docs, or anything else, I can easily magnify the text with little effort. I never did this before because it required too much effort on my part, but now I don't know how I lived without it. My eyes are really thanking me for this.
The only really useful muti-media functionality are the sound and play/pause keys. Since I use my headphones a lot and the sound is always blaring through them, I can quickly turn down the system volume.
If I had to, I would buy this product again.
