Here is a face to face with the initiative taken by Sony to in account of beta version PS3 network or you can simply call it as Sony's online strategy for PS3 sited over Eurogamer. The long article makes familiar with different aspects, some of which are discussed here in nutshell:

PlayStation Store will attempt to provide the free and paid game contents with a wide range of included new titles particularly for download to wrap-up more than just new game content and demos.
Booting up the PS3 gives you a Cross Media Bar (like the PSP). The phenomenon is just to show the regularity among their products. It also provides multiple user profiles encompassing personalized settings.
We can call it a pretty nice online strategy.
