For Blu Ray, DVD, Internet, music, pictures = YES ----- For games (r) = NO

If you use the PS3 ausschhließlich to gamble on games and looks sometimes even a DVD or Blu Ray, so the controller goes completely. The all important functions (if maybe a bit awkward) perform with a few clicks.

If the PS3 but as an entertainment console used (DVD, Blu Ray, music, Internet, pictures, etc.) so no one gets past the Remote Control.
Almost all the Blu Ray disc have a pop-up menu for extras (bonus material) which is eg. not or can only in a roundabout way to the controller open.
Playback on Blu Ray, easy title selection with CDs, simply entering the Internet Explorer fix Auwwahl or programming switching of extras before & WHILE in images (books) - These features come as.
This and much more work is with the remote control from your sofa and who else other SONY devices be called eingen it can operate with the same - It is not a trick, it is a SONY :-)

CONCLUSION: Who's Playstation 3 should not be used for games ONLY / must have the remote control.
