I can't battle my buddies or family members or friends on PSN, cuz they all have Xbox. Free PSN won't help me there . But I am glad PSN is free since I don't use it that much. It would be a waste of money (just like Xbox would be a waste if you didn't use it much) if they charged for it. BTW, new PSN Store is coming out next weeks! Looks tits!
Yeah looks like it got alot of inspiration from the Xbox Live dashboard. But thats a good thing.
