Best for what?

For programming and writing, I'm extremely happy with my Microsoft Natural Ergonomic Keyboard 4000. No interference, pairing or batteries to worry about - just plug into the USB port (1.8 metre cable) and off you go. The key travel and resistance is just right, so that my fingers don't tire after a whole day of work, and the ergonomic design helps against wrist pain (I've had that with straight keyboards). It does have numbers, though: both in the top row and on the numeric keypad (not sure what your issue with numbers is, they're quite essential in all the typing I do).

It also has some cute additions like the zoom lever, browser and multimedia keys, but that's just icing on the cake :)

Another vote for the MS Natural Ergo 4000. I've bought 3 total, on two continents. My wrists also feel better than with a flat keyboard.
