Dude , i think you haven't heard about the
Xbox 360 Elite , it retails for 480 USd and comes with 120 gig HDD , HDMI(with cable that is) and all other features . Which , is $20 cheaper than the cheapest PS3(USD 499 60GB version)
One Advice

lease verify your claims before making them .
Mate , the PS3's SPE's are specially designed for streaming floating point operations(i.e. gaming) .
Just like a GFX card outperforms a CPU in gaming , a CPU can outperform a GFX card in normal computing tasks
I was eagerly waiting for both the consoles and after a lot of brainstorming , i have come to the conclusion that the 360 has won the 7th Generation Console War.
and for your info , i own a PS2 and seriously believe it to be the best console of the last generation . But the PS3 is a disappointment , and it's selling only because it's a sucessor to the legendarry PS2.
Also , as for PS3's multimedia capabilities , well the 360 too can play media files from pen drives and can do al sorts of Multimedia tasks like playing movies , etc so both are same here.
And the biggest hing is that the 360 is made by "Microsoft" , and with the current amount of money they're putting into 360's marketing and exclusive content(GTA IV anyone) , and the numerous features they're adding in the software updates , i'll place my bet on them .
