While working in Photoshop and CAD I've always wanted physical, dedicated buttons to perform certain oft-repeated actions, but my laptop's QWERTY ain't got the space. Could this be the answer? The DX-1 Input System has 25 programmable, label-able keys you can stick anywhere on the transparent tray, which you can also slide labels under (like the transparent sheet on top of a Wacom tablet). It seems better to me than that Optimus Maximus keyboard with the LCD keys, because you can actually select the layout here and sort of tailor the ergonomics.
No mere concept, this thing is actually in production and for sale here.
