One of the things I love about playing RPGs on a handheld is I can close my 3DS or put my Vita to sleep and I can continue right where I left off without having to look for a save point. PlayStation 4 will have a similar experience.
Sony Computer Entertainment says PS4 will have a "suspend mode" which keeps the system on, but in a low powered state. Since the system is still activated players can jump back into a game and continue where they left off without loading a saved game. That’s something to look forward to for the next Final Fantasy title.
Console updates and game downloads can be done while the system is in suspend mode. You can also play a downloadable game while it’s downloading. PS4 only needs to save a fraction of the data for the game to start and the rest will be downloaded while you play the game. PS4 also allows players to run apps like a web browser while playing a game.
