After years of false-starts and not-quite-there implementations, it appears that the connected TV revolution is upon us. Finally, consumers will have access to affordable technology that will let them access web content and content from their Macs or PCs from the comfort of the couch, without expensive HTPC setups or complicated software. The battle for the living room is finally here. Three of the big contenders in this space are the new Apple TV, the upcoming Boxee Box, and the recently updated Roku XDS. All three units work without a hard drive and stream content in HD from the web to your TV. All three also offer the ability to access non-web content too (via add-ons or over a network).
