Microsoft Vista Media Center has come a long way.  It is a stable and reliable whole-home entertainment platform.  Media Center Extenders (MCX) extend the complete experience currently to up to 5 additional HDTV's [if the 6th is the Media Center itself].  MCX's have been coming out from everyone from Niveus Media, HP and Samsung to Linksys and D-Link.

Engadget has a good review of a couple of current Extenders, "The Media Extender Shoot Out".  They don't cover the newest and unreleased Samsung and HP MCX's, but do represent the XBOX 360 and current crop of other MCX's.
