While not much larger than the standard computer keyboard, the ultra-thin Optimus Popularis keyboard packs infinitely more power. Not limited to English characters and numbers, each key can be assigned nearly any function: Ancient Greek alphabet, music notes, math functions, images, and more. Whether you're a designer, musician, typesetter, or translator, you can set the keys to accommodate any language or set of symbols—in any layout. That's total control at your fingertips. Available at artlebedev.com; $1,500.
