I dont know why people act all suprised when they see this sort of behaviour from Apple.. I have never seen so much lock in from one company (and no, MS are no where NEAR as bad as Apple for product lock in).
You buy your overpriced iMac, iPod, iPhone, iCantThinkForMyself all of which will only work as they should with each other, failing to realise that Apple are ALL about control.
Always remember, just because MS aren't perfect, it doesn't make Apple good.
MS are bad for smothering the market, yes, but they are getting better, more open. They are starting to realise they cant go on pissing off the masses and losing market share. I can happily go home to my "buggy, bloated OS" and do what the hell I want with it, connect pretty much any device, whatever.
Apple seem to be going the other way, more closed doors, more lock in, less interop. I just feel for the many people that have shelled out a lot of cash for a crappy over-hyped product by a crappy over-hyped company.
