Besides of course removing the "Other OS", there is a list of the other small changes in the features and operation of your PS3 now:
* Other OS deleted (of course, we knew that was coming!)
* Default System deleted (I wonder why?)
* The playback quality of some PlayStationŽ format software that is downloaded (as a purchase or for free) from PlayStationŽStore has been improved. wee..... (Big deal, where is my $600 Linux box gone?)
* A security patch was added to address security vulnerabilities that may occur when playing MP4 format video files. hmm.... (That is a neat one, never heard of this "security" problem, before!)
SO IT SEEMS DEFAULT SYSTEM WAS DELETED ANYONE CARE TO EXPLAIN WHY?
