I’m not sure yet what I’d do with it, but the Optimus mini-three keyboard looks very fun: it’s an auxiliary keyboard with three keys, each with its own little OLED screen displaying the current function (potentially animated). The most compelling examples are where not only is the button’s function displayed but also what effect it’ll have in the current context, like what image, song, or PowerPoint slide is coming up next when browsing through media.
USB 1.0, currently Windows only for the configuration software but others are coming. Pre-orderable for $100 until April 2nd, shipped to arrive on May 15th. This is coming out of the Art. Lebedev Studio in Russia — looks like they’ve also got a complete keyboard coming soon too.
