New to PS3 version 2.5, also available Wednesday, are more than a half dozen updates, including screenshots, which like a "print screen" function to save in-game images directly to your hard drive using a keyboard, and auto-off for idle controllers to save battery life (nice!).
Also new to PS3 firmware 2.5 is a standby option to auto turn off your PS3 after 1-5 hours of use (much like Xbox 360), Flash 9 support for the PS3 web browser, improved trophy management, the ability to see when a friend last signed on, and a faster PlayStation store.
Not a bad deal for being free. What do you think of the updates? (My favorite is the auto-off controller -- lovely.)
