Maltron's Dual-Handed Ergonomic Keyboard
$600

This one offers a freaky sculpted design with keys laid out in five distinct blocks. Maltron says it takes three to four weeks to adapt to the layout, which is more time than most entrepreneurs are likely to have at their disposal. While I found it awkward, this wired keyboard might be a good choice for business owners with a history of repetitive-stress injuries. Oh, and deep pockets.
