I saw another MacRumors poster suggesting that the Time Capsule should give you the option to automatically & wirelessly back up your iOS devices -- either in place of or along with iCloud backups. I think that would be pretty easy for Apple to do.
The only thing that other wireless routers are doing is putting in bandwidth shaving to custom set or bias to 4K streaming devices! Plus with all the hacks of these new remote features and hackers are taking great advantage of those remote features!
IMHO with Apple Routers you have to use Apple software to get into their routers and they look inviting for sure!
