We have reviewed many keyboards here in AnandTech, both electronic (membrane) and mechanical. In today's market, most cost-effective keyboards are based on membrane designs, while more advanced keyboards are using mechanical switches that are either made by Cherry or, usually, are a "cloned" version of their products. Recently however we had something relatively rare shipped for testing in our labs - the i-Rocks Pilot K70E, a keyboard with unique capacitive switches.

Capacitive switches are not something unique to this keyboard. As a matter of fact, the current top-of-the-line capacitive keyboard switches were introduced by Topre several years ago. The problem with Topre-based products is that their prices are excessive, placing them well outside what the mainstream market can afford.
