Watts... uh THE DEAL Promising 75 real-world watts for each of five channels, Rotel's silver giant has the power to justify its heft. And 7.1-channel home theater buffs needn't fear - you can add an extra two channels with an optional upgrade. Bring on those action flicks!

Keep It Real It's kind of a bizarre resolution for a plasma TV - 1,024 x 1,080 pixels - but Hitachi just might know what it's doing here. Those 1 million pixels are driven by a technology called ALiS (Alternate Lighting of Surfaces) to get the most detail out of 1080i signals (the most common HD format) and bestow a smoother, more filmlike picture.

Thanks to their portability, personal navigation devices (PNDs) are finding their way into the hands of more and more drivers of multiple vehicles. PNDs not only assist in getting you from point A to point B - as well as locate every ATM and Starbucks in between - they also offer features such as MP3 compatibility and real-time traffic info.

NO WIRES The Philips Streamium music system takes all the complexity - and cables - out of multiroom audio through the wireless magic of Wi-Fi (802.11g). As soon as you turn on the WACS700 main base (left) and its satellite, they automatically find each other - no pairing, seeking, or inputting required.

NUMBERS GAME The hot spec on HDTVs this year is 1080p resolution, and the Sharp Aquos LC-37D90U 37-inch LCD joins the crowd with a 1,920 x 1,080-pixel screen and a 1080p input. That means it will not only show every last detail of a 1080i HD signal, but that the display is pretty much future-proof - until they start broadcasting holograms.
