I'm a bit concerned about all the people here that tell they've been using Google services for decades and are afraid to loose their pictures/documents/etc... I mean how is giving such control over your data to one company a good idea in the first place ? I'm not saying that in patronizing way, but this should not be considered as normal behavior. I think that Google has already access to way much more data than it should and I really wouldn't want to hand them my phone bill. Even if you're not concerned about your privacy (and I really think you should), centralizing everything will only make problems worse if something happens with this one service, should it be Google, Apple or anyone else.
