Exactly! its how it works, they couldn't exactly say hey here is light weight PS3 and look Now we've just released a BIGGER HEAVIER ONE! just wouldn't work lol
Everything has to get smaller with new technology, however if making it smaller only makes it worse then whats the point
id happily buy a bigger machine if it was better like the ps3 orriginal was out when the ps2 slim was out i went for the better machine not the small light one
