So you got yourself one of those fancy new Sony 3D HDTVs, but the set only came with a couple pairs of glasses at most, if they came with any at all. Well, Sony’s got you covered now, since they’re selling the active shutter glasses separately at the Sony Store and other online retailers for $149.99. They even come in smaller, children’s-sized versions with fancy colors (for the same price). That’s on top of the IR transmitter ($50), and the 3D Blu-ray player that’s either a Sony brand or the PlayStation 3. But such is the cost of being on the cutting edge of technology.
