My big concern and I've expressed before is about many, many folks having no idea what these changes are and what to do with app library, etc. I would think a vast majority of people never change screen layout or do anything with wigets etc. So are they going to be very confused with all this new look stuff. I know I'm thinking of going out of town when my wife gets this update.
You're correct...I think of my parents who most likely don't even use folders. This is perfect for them. Just delete all their current pages and leave them with App Library. And honestly, I think this is the majority of iPhone users.
We here on MacRumors are the minority and like what we like and know how to use the system to it's full extent. As shown by most of the comments on here, App Library as simply "too simple" and not customizable enough for some. The answer? Don't use it!!
This is such a rare situation...Apple has actually added a new feature (or features if you throw widgets in here as well) without taking away any of what we were able to do or organize like we did before. But for the vast majority of users that download hundreds of apps and they just sit on multiple pages, this is a great option.
