Using the virtual PSP, you can jump immediately to any place you want to go to. At least, to any room, that is. Like, you can jump from your apartment to the arcade instantaneously, but you'll still have to walk fro the pool table to the bowling alley, I'd imagine.
I can't believe how excited I am about Little Big Planet though. This might actually force me to start making friends online

Don't kow that I have the patience to make anything
near a decent level. Same reason I've only ever made 2 AMVs. But being able to upload them and have anyone play it should be a really cool feature.
As for Home, there's still no real guaruntee I'd use it, because I rarely talk to people online as it is. I only have 3 people in my friends list. But I still appreciate the use for the technology. And letting private businesses have their own rooms is genius. I could imagine going into a 24 room or a HEROES room or something like that, with just the thematic atmosphere of the show and nothing but fans in there. Or if a developer wanted to give a talk, instead of duing it via forum Q&A, they could use this virtual medium. I'm sure Sony could whip together some kind of auditorium for this, and people could actually
sit in the audience and listen to him talk, and ask questions.
