Based on some of the comments posted, I would like to argue in both directions. First, I agree that Apple has not taken their services to the same level of "spit and polish" as their hardware. They need to continue to invest in improving services - most importantly is iCloud and iCloud drive. But you can run the gambit - Music, iWorks, Photos, Siri, Maps. Focus must be maintained on the original vision of doing a few things great.
The problem is that while they focus on what they already do, new things and opportunities come up. Should Apple simply miss the boat and hope to come late to the party and still be a disrupter. I think they certainly were (okay lets agree on will be) with Apple Pay. But with Music and streaming they were way too late and it will really take a while to be on par with the competition, but a disruptor I just don't see right now. I have no idea how real this rumor is, but I would say there is still an opportunity in this space to change the world. We are still beholden to the networks. Netflix, the king of the hill right now, has yet to break through the network. I cut my cable, but its not easy and you cant get any current content. With Amazon and Netflix starting to create their own programming, things are about to change. And here there is an opportunity.
Maybe this is like Beats and Apple buys out Netflix or more likely someone smaller like Hulu and builds on that. For me the key issue is that while they must be laser focused on existing lines to be the best, they should also continue to seek opportunities to disrupt new lines of business. Their attempt in the music space has not worked well (oh, they may still do fine. my point is that they have not disrupted anything, yet). If they decide to go into this business let's hope they really do Apple justice and find a way to disrupt. The first clue as to how well of a disruption they can achieve will be with the announcement of the new AppleTV which will be the platform that any service will center on.
