You'd think for $50/60, a keyboard maker would put letters on the keys that wouldn't wear off, wouldn't you? Ridiculous. "N" is gone, "E" and "A" are fading fast, "C", "M" and other high-usage fee showing lots of wear. Maybe Logitech could spend another 5¢ and fix the problem.
Great keyboard in most regards; Responsive, good battery life, good wireless
