Maybe I'm a minority, but I've been happy with my 10-year-old Das Keyboard (cherry blue) for home usage and 4-year-old FILCO Majestouch (cherry brown) for the office. They're "boring" - they don't have anything fancy on them but they look like keyboards and they're pleasurable to type on.

Recently, I thought of replacing my Das Keyboard and tried to get something equally "boring" - it was sad to see that they don't have the boring option anymore without at least one or two spinny wheel or flash function key.
