In a move that could further point to a “headless iMac” at Macworld Expo next week, Apple has quietly reduced pricing on its Cinema Display lineup by as much as US$300. The company is now selling the 20-inch model for $999 ($300 less), the 23-inch HD model for $1,799 ($200 less), and the 30-inch HD model for $2,999 ($300 less). All three Cinema Displays are immediately available.
