HP MediaSmart SL4282N and SL4782N HDTV with Media Center Inside

The Skinny: MediaSmart 1080p LCD TVs are coming of age—both the $1,900 42" and the $2,400 47" will have built-in Microsoft Media Center Extender connectivity and an improved higher-contrast panel (2000:1). They have 3 HDMI ports, 2 component inputs, integrated Wi-Fi in A, B, G, and N flavors and Ethernet. Has ATSC and QAM Tuners and 500cd of brightness.
One catch: Though you can rent movies without your PC, the PC still needs to be running, and there's a bit of a delay.
