Long live the phat PS3!!!
Ill be keeping mine like I had with my phat PS2, both arent going anywhere even if they were to stop working (well ill try to get replacement for them but of the same thing).
I know the slim has some interesting advantage has been more light, smaller and probably more silent (this will need to be proven has I seen 40gb much more louder than my original 60gb), matte finish (ahhh no more annoying dust, fingerprint scratch). But no BC, no media slot, 2 usb and no more Other OS. All features I am currently using so the slim cant replace my current usage of my phat PS3.
I wish you all that are keeping their phat PS3 it will live long and prosper (doing the vulcan hand sign ;-)).
