Here's an excellent (and funny) overview from Ars Technica of different kinds of switches in keyboards. http://arstechnica.com/gadgets/news/2011/02/ask-ars-ergonomi...

The "Happy Hacking" keyboard looks very nice, and has no numeric keypad. But it's ridiculously expensive. edit: apparently RMS http://geekhack.org/showthread.php?13526-Richard-Stallman-%2... and Bjarne Stroustrup http://geekhack.org/showthread.php?18556-HHKB-spotted-on-des... use them :)

To actually answer your question, the wireless Apple keyboards have nice scissor switches and are surprisingly decent to program on. And no numbers on the side!

I'm a huge fan of the Happy Hacking keyboard. Everything feels so close on it, and I always find myself wishing I had one when I have to type on other keyboards for a very long time.

I have a "Happy Hacking Keyboard Lite 2" that I bought from an old co-worker. It's noisier than the apple keyboards. The keys are loud, but it's a great keyboard. Once you get used to it, you don't want to use other keyboards. My co-founder has the pro and the action is better. The keys are a little quieter too.

I've been using the Happy Hacking Keyboard Lite2 for a few months now, and I can't imagine going back to anything else. Its small size and intelligent, minimalist layout just works for me.

It's well worth the $70 I paid for it.

I second this, I've been developing with Apple wireless keyboard for years now, and I love it mostly because it's really small and I can access pretty much all the keys without moving hands much.
