I really hope that Home on PSP is not just an AIM-like messenging thing. As much as I'd love to have a PS3 to use Home on, I can't afford another expensive toy. My PSP cost me enough money already. However, I may consider finally buying a PS3 depending on whether or not the price drops within the next year, and if they do not make Home on PSP mostly like the one on PS3. Just because I really think it will be a cool and fun feature to use.
I think that a extension of Home would be a great idea. Like the idea for using the PSP as a rear view mirror in f1, It could be cool to use the PSP and camera to use as a video feed to others so that the game play would still take the full screen on your PS3 system. Or for a chat window to be open on the PSP while playing on the PS3, Or a map to be active on the home community on the PSP with dots indicating other people/friens or buddies/ or enemies - if we will have such things in there.
Defiinetly also accessing the entire home metwork while on the go would be a great advantage!
