> By purchasing Lala, Apple acquired technology that would enable it to bounce everyone's iTunes libraries to online servers, so iTunes users would be able to access their collections from a variety of Apple's devices: laptops, desktops, Apple TV set-top boxes, iPads, iPhones and iPod Touches. [1]

I never used Lala, but I have used the iTunes "Sync Library" feature. So, in my case, yes I suppose I benefited from that acquisition.

Not claiming that "we all" benefited. But this seems to be another case where Apple bought some company for its technology, folded it into its own service and made it available to a much wider audience, and then killed off the original service. If you were a happy Lala user, then I think your disatisfaction is justified, and you certainly have my sympathy. But also need to recognize that Apple was able to reach a far wider audience with that technology than Lala did.
