For the past 15 years or so, I have been using a TypeMatrix keyboard (2030 USB, Dvorak). For me, the best part of the keyboard is the ortholinear layout. This is really a great feeling to just extend/retract a finger to reach to above below row. It has dedicated function row (which for debugging is for me a must have). I would recommend anybody with pain to try an ortholinear layout, be it from company X or Y, I really think it is a massive improvement against the standard non symmetric layout.
