PS3 needs the date/time in the top right corner of the XMB screen.
And the PS3 needs a Download Scheduler. Currently, I have to manually start my demo downloads at 3am so I catch them while off-peak.
I wouldn't mind an Idle Time Shutdown. But I don't really need it. I either run F@H 24/7 ... or I turn it off. I never 'forget' to turn it off ...
