I dont know why anyone's surprised at this, Sony always -remove- features in their consoles over time.
Hard luck for anyone actually wanting/using those features.
Many of the "more interesting features" are just early-adopter fodder, once the console breaks the mainstream, Sony's loyal, premium-paying fanbase are soon forgotten.
It's a process they've gone through again and again and each generation the suckers come back for more.
-Cell started out as the "be all and end all" of CPU architecture and was quickly proven to be more exotic headache than paradigm shift.
-BluRay was plugged as the must-have format for HD viewing but it's now more meh than yeh.
The shine of Sony's hype soon wears off like chrome plating on cheap plastic.
Personally, I treat consoles as gaming appliances nothing more. If they happen to be able to do other things, take it as a bonus but expect that the copyright owner can at any time take their toys away making the system unusable for those things.
