I don't know that I necessarily agree with that. 'Pro users' are typically defined as those people that use their computers, at least in part, to make a living whether that be artists, audio/video editors, film makers, software engineers (like me), etc. Having a focus on letting the tech get out of the way, so what the user interacts with doesn't feel like they're manipulating tech is a good thing for all those folks, IMO.
iCloud is a perfect example. The fact that so many of my apps (Messages, Safari, etc) use a cloud based service to keep things in sync, to keep my messages in all places at all times .. but it does it automatically and without me having even know that it's happening .. is a great example of letting consumers benefit from high tech while still keeping it in the background. It becomes a smooth experience, with great empowerment, but the user isn't tied up in the details of it all. Companies that simply work at building tech place the consumer experience as secondary, and that rarely helps anyone.
I think being focused on the consumer experience first, and building tech to provide all this functionality with that priority is what helps everyone have a more enjoyable and more productive experience.
Agree that the professional cannot afford to be distracted with tangential things like storage or email or maps. But while it's good for consumers to have the workings of a gadget or computer hidden away, the professional needs access to the inner workings, especially as much of the job is about dealing with novel challenges that require new solutions or to improve or refine performance. The product suited to the consumer is very different than the professional product. Cook's quote says Apple is focused on the consumer and I don't think it's any different than Jobs's. The Apple pro golden years are an aberration.
This Apple vision explains why Jobs didn't want larger screens - because the iphone 4 is a good fit with the hand. If you want a bigger screen then get an ipad. Lighter and thinner is not about technical triumphs but because lighter is easier to use and less intrusive. The iwatch isn't a silly gimmick but the natural progression from the smartphone to something even less intrusive (better than awkward and threatening eyeglass like stuff from google), though the technology isn't ready yet.
