The test lab at our review partner Digital Trends tested the expensive OLED keyboard from Art Lebedev, the Optimus Maximus. The unique keyboard did not fair too well in this review with negative points that include high price, poor typing ergonomics and questionable long-term reliability.
Quote from the review: "Thanks to a glowing array of 115 individual OLED displays fitted under its keys, Art Lebedev's Optimus Maximus is the first and only keyboard that literally morphs before your eyes. Pressing shift and watching all the letters beneath your fingers leap to caps gives you some idea what the Maximus is capable of, and why it's become one of the most hyped-up, fawned-over and generally talked-about devices on the Web. While it delivers sheer novelty value in spades, we found that its princely pricetag, layout and reliability woes may threaten its practicality as a typing device."
