Japan loves silly ideas. We're the country that came up with the humping dog USB thumbkey, after all. However, sometimes that idea philosophy results in surprisingly useful inventions.
One of the primary issues that touchscreen critics have is that typing on an onscreen keyboard is damn near impossible. Whereas a plastic keyboard lets you rest your fingers on the home keys and only register full presses of each key, touchscreens require your fingers and your hands to awkwardly hover over your screen, pecking down one by one and hoping that it hits the right 'key'. Your hands drift a little to the right or the left, and you end up with something like: wgere ig wgere gas nt kuttke dig gibe. While the iPad keyboard is pretty large, it doesn't completely solve that problem away, despite the fact that many people have migrated to doing full typing work on those tablets.
This product takes the problem-solving a step further. Let's give your tablet keyboard keys edges! At least then, your fingers can intuitively tell where the edge of each key is, and adjust accordingly.
This keyboard bracket is compatible with the Japanese and English, German, and Chinese Pinyin keyboards - it is unfortunately not compatible with the French. No others were tested.
