I don't think that a company having it's own ecosystem is a bad thing really - it's probably a better thing in some circumstances but I suppose that's all down to what you believe and how you want things to be. If PlayStation have their own shop, then so be it - I can buy the games elsewhere still though. In the case of Apple, that's where I would draw the line a little bit. It's annoying when things are 'exclusive' to somewhere. Like I said, I can buy a PS game from the PSN store or I can hop down to my local supermarket or I can add to my basket on Amazon. Have your own store in those circumstances but if you're feeling a little 'Apple-esqe' style ecosystem, then no thanks.
