Oh yes I love mine.
Its pretty old now, like 3 or 4 years. Its one of the Microsoft Natural ones without the internet keys.
I don't think I could go back to a regular one. Typing on a regular keyboard after awhile made my wrists hurt, but its a lot better with a ergonomic.
Took me awhile to get used to it though, thats the only thing I could say negative about it.
ergonomic keyboards = teh best!
