HP has updated its MediaSmart TVs for the new year. On the surface, the new SL4282N (42-inch) and SL4782N (47-inch) are very similar to their 2007 counterparts: full 1080p resolution LCD flat-panels with 3 HDMI inputs, built-in high-def and analog tuners, and--the big differentiator--the ability to stream digital video, audio, and images via their built-in 802.11a/b/g/n wireless networking connections. But the big upgrade for 2008 is the inclusion of Media Center Extender functionality, which offers easy connectivity to PCs running most flavors of Vista.
Prefer a non-HP TV, but want those same media features? HP's got you covered there, too: the company's external MediaSmart Receiver x280N attaches to any TV and delivers the same functionality.
