I’m pretty picky about my computer keyboards (and have been since using ‘dumb’ terminals way, way back). So I’m always interested in links to new ones.
So far my preferred keyboard for both Mac and PC has been the Microsoft Internet Pro keyboard (with the built in USB hub). However, it got stepped on the other month (don’t ask) and will need replacing at some point soon. They don’t make it any more so it’s time to look around.
