Details of the upcoming 1.6 update have been revealed, and many PS3 users aren't happy. It seems that Sony allows game developers to use all of the console's memory for their games, whereas Microsoft has intelligently reserved 50MB for system use. And this is where the problem lies. Since the PS3 uses all the system's memory for games, background downloading while a game is running is impossible. When you download the 1.6 update for your PS3, background downloads will pause while you play games.
