Is there really any such thing as "too big" when it comes to a television? Panasonic obviously knows that most guys don't think so. The company just unveiled a new 103-inch high-definition plasma TV that'll arrive under the Christmas trees of some really lucky — and astronomically rich — fellas this holiday season. Such gargantuan plasma TVs have generally been trade-show-only fare, but the TH-103PZ600U is the first panel in this size (which is the size of four 50-inch displays) actually available to consumers. Of course, a 103-inch TV doesn't come cheap; the Tyrannosaurus Rex of plasma displays is built to order and will be available exclusively from select high-end retailers for the princely sum of $70,000. But to the guy who truly has everything, size probably does matter. At least the price tag includes a three-year in-home limited warranty — it had better, considering that the set costs more than a Porsche. Then again, if you had a wall-size 1080p HDTV, would you ever leave your house again? — Peter Suciu
