Separate thumb keypads
The thumb keypad includes often used keys such as Enter, Space, Backspace, Delete and the combination keys, Control and Alt on the PC (Command and Option on the Macintosh). This redistributes the workload from your relatively weaker and overused little fingers to stronger thumbs.
Separate key wells for each hand
This separation minimizes strain and stretching by positioning your arms approximately at shoulder width and with wrists straight. This design reduces abduction and ulnar deviation (common symptoms experienced with repetitive strain injuries such as carpal tunnel syndrome and tendonitis).
