Good thing about PS3 is it has WiFi so it's nice and easy to update. But for standalone BD players, I can see how it'd be a PITA.
My girlfriend's parents got a BD player and it wouldn't play their discs, so it had to be updated. They had no idea wtf was wrong (as most of the average consumers don't). It's really unnecessary imo.
Look at HDCP. Everyone had to move to it, and now it's pointless. SSDD.
