>>> Just wish that my Apple devices could integrate with Echo that's all.
They do; you just haven't had the Echo long enough to explore all the ways. Using my iPhone I can play ANY music stored on my home network to Echo; play stations not in Echo (like Slacker), all done with the aid of Bluetooth to my Echo. Search this forum for "Bluetooth" for some ideas.
Many of us wish the Echo could access our home network, rather than using BT as a bridge. but so far we can't. You have to realize that Amazon is all about selling other Amazon products, and not other brands. So, the Amazon products integrate best with their own products, like Alexa and FireTVs do.
As you spend more time with your new Echo and peruse this Forum, you will eventually get up to speed with how it all works.
