The PS3 is now available in the US and, for those lucky enough to have one, the system's online service has now been activated. Much like Xbox Live, the service provides a store where PS3 owners can download demos, game trailers and full games.

Available to download from day one are demos of Resistance: Fall of Man, Motorstorm, NBA '07 and Formula One Championship Edition. You'll also find two full e-Distribution titles available to purchase: Cash Guns Chaos and Blast Factor. There's also a selection of game trailers and some other high definition videos.

The PS3 launched in the US in the early hours today, details of which you can find here.
