Tom's Hardware is reporting that the Optimus keyboard that everyone was so anxious for (although maybe less so when they saw the price tag) started shipping this week. "According to an announcement made on the Optimus project blog, keyboards are now shipping to customers who pre-ordered the $1564 keyboard nine months ago. Keyboards with passive keys are delayed and will be shipping in about a month, the manufacturer said. [...] Earlier this month, one of the first Optimus Maximus keyboards was sold for $2750 on Ebay." Engadget even got the chance to test one of these expensive toys out.
