Remote Play is one of the more exciting things about the PS3-PSP connectivity. It's a nifty feature that allows you to access your PS3's media via PSP. While cool in theory, in practice, there's too many restrictions. Firstly, the PS3 can't do anything else when in Remote Play mode. Secondly, you have to be in range of the PS3's wi-fi. Finally, you can only access media stored on hard drive (no games, or disc media!).
It appears that a future firmware upgrade in March will address some of these issues. The future PLAYSTATION 3 upgrade promises multi-tasking, which should help address the first concern. Secondly, you'll be able to access your PS3's media from any internet connection, a la LocationFree Player. Certainly, this is a strong step forward. With the PS3 gaining Tivo-like functionality later next year, the PSP may be the perfect media device for people on the go. Imagine: you could record Battlestar Galactica when you're away, only to watch it from your PSP whenever you're near a wi-fi spot. The future of PS3-PSP connectivity is certainly exciting.
