> Shared iPad requires a device management service and Managed Apple Accounts that an organization issues and owns

I don't want to have to do a bunch of sysadmin just so my wife and I can both see our own YouTube subscriptions on an iPad. Again, you could do this with zero fuss in 5 minutes on Windows XP.

This sounds like a business opportunity. I have to learn more. Imagine a family MDM service. Would be cool.
