The Kinesis Freestyle Solo Keyboard (discontinued) has a traditional but compact key layout which makes adaptation a breeze, but that's where the traditional keyboard design ends. The Freestyle Solo consists of two keying modules connected together by the flexible Pivot Tether, which allows infinite adjustment of the front opening angle (splay). Removing the Pivot Tether allows the two modules to completely separate up to six inches, accommodating a range of shoulder widths. The narrow footprint allows a closer reach of a mouse. The new model is the Freestyle2 and has all of these features in an even lower-profile design- available in USB or Bluetooth and PC or Mac variations.
