Here's a nice article in The Register about Logitech's newest ergo keyboard. It has excellent pictures to go with the text.
First there was the Microsoft Natural. Lots of folks loved it. I couldn't stand it and so have stuck with "standard" shaped keyboards. Yes, there were other ergo keyboards but because sales were so slow, the cost of such solutions stayed out of my reach. Or at least higher than I could justify.
Now, it seems that Logitech has taken pity on me. This new keyboard looks good and is affordable. I'm going to get one as soon as they arrive in my neighborhood.
