ERP said:MS is a software company, Sony is primarilly a hardware company.
Except, in the console sector it's Sony who has the advantage (by far) when it comes to software. So, I really don't see what you're getting at here.
It's not like Sony's going to forget what put them where they are, or what's keeping them there either for that matter... (And no, before anyone answers "hype"; that's not it. )
