The latest updates for the PS3 and PSP adds a pretty fair amount of useful functionality. You can customize when your PS3 and controllers go to sleep, and can set your PS3 to shut down after finishing a big download. There’s support for the new SOCOM bluetooth headset, you can now see more info on friends who aren’t online, and you can take screenshots in-game now, if the game so allows. I’m a stickler on power consumption so this update sounds pretty awesome to me.
The PSP now can access the Playstation Store directly and download games whenever it’s in wi-fi, which is pretty awesome (it uses the same account as your PS3). They’ve also added a full-screen keyboard and a sleep timer for mp3 playing, both of which fall under the “oh yeah — I guess I did want that” category.
