It looks as though the Optimus Maximus may have some competition
. United Keyes is rolling out a keyboard that is very similar to the Art Lebedev keyboard. I guess now it is a race to see who gets their products to market first.
A fundamental difference between this approach vs. touch screen is that the tactile feedback associated with pressing a button is retained. This promotes familiarity. A second important advantage is the ease of modifying existing form factors, reducing time to market and component costs.
