Complete cellular data coverage would have to happen before I'd opt for cloud ownership over file ownership. Things to consider... What about all the areas where data service is less-than-fast? What about the areas where there is currently no service. Will I have to pay for wifi on a flight to listen to my music? I also believe the same questions can be asked here as you have brought up before with respect to DRM. Why buy access (cloud music) that is locked to specific service providers (lala) when you can buy files that work with any product (machine-based media players, ipods, lala, etc.).
