While I love the keystroke feel of both wireless Apple keyboards, I really wish they had a split ergonomic version. After a day of coding, my wrists and for arms just ache constantly.
Or ......maybe this is on HN for some other reason.
I have a Kinesis Advantage keyboard at work, and let me tell you, it's an unbelievable pleasure to work with. No pain or aches in my hands or fingers at the end of a work day. It's a hideous beast, but my god, is it worth it or what... People also say that the keyboards have lifespans of ten years plus. http://www.kinesis-ergo.com/
It's not pretty, and it's certainly not cheap, but it's one of those investments that makes a huge impact on your happiness, like a quality mattress or a really nice kitchen knife.
Again, I can't recommend this keyboard enough.
The darkness makes it clash with Apple's aluminum color scheme though, so they're not ideal desk-buddies.

I'm not at all convinced that "ergonomic keyboards" necessarily are that. But if an organization is serious about having ergonomic solution, they have to make it default, not option you can choose later ... 'cause the vast majority of people stick with the default option.
