We only have the iPod, iPod touch/iPhone, apple TV, battery covers on newer Apple laptops, and Apple's hardware for their computers to show where they are headed. Some may accuse me of a slippery slope argument; I look at it as a continuation of a linear regression and projection. And where that's going doesn't look peachy.
It is a rather interesting point they do not have any GPL 3 software distributed, and for probably for both the reasons stated. However, the way the whole Mac feel is as it was a curated device (regardless the actual platform). Both Apple and Microsoft seem to want to converge on a "trusted platform"; where the trust is against you.
"Slippery slope" is a specific type of usually-fallacious argument that relies only on what is possible, not what is likely based on actual evidence and trends. It's not a generic term for any argument that seeks to prove "X is heading toward Y".
