Ok, I dont have my PS3 yet - it gets deivered on thursday (Hooray!) and I hadnt even looked into that sort of thing untill I saw this thread. Had a look at what 'Home' is and it looks great!
I'm very pleased the online gaming network is free but i didnt know this was in with the deal too.
Do you know if there are different networks for U.S. and U.K. or can they 'see' each other?
