I remember wanting an evolution keyboard mounted up to an aeron so badly back in the day but sadly I discovered them a year after they were discontinued. http://deskthority.net/photos-f62/ergonomic-keyboard-parade-...

I'm swapping between ergodox, kinesis advantage, and type matrix these days but always keeping my eye out for a better solution. Honestly the best thing I have found is a different keyboard, so these days I just keep cycling through them every few months.
