This year most major TV makers are using interactive features to distinguish themselves from the others, and unlike differences in black level performance and off-angle viewing, it's easy for shoppers to tell the various interactive add-ons apart. Whether they actually want said add-ons is another question.
Sony's KDL-W5100 series represents the company's most affordable attempt at interactive TV, although it still costs a few hundred more than the entry-level Internet-ready sets from its competitors. Sony does offer a lot of extras, however, including select Yahoo widgets, scads of streaming Web video (much of it pretty niche), Amazon Video on Demand, YouTube, Shoutcast, and, coming soon, Netflix. The latter will propel the W5100 and other interactive Sony series past the current content-on-TV champ, LG's LH50 series, in the add-on arms race. Meanwhile the W5100 delivers better picture quality than most standard LCDs out there, making it a well-rounded package if you have the extra cash and really want streaming video on your TV.
