I am sure this has been covered before, but I did a search and couldn't find anything. I just got a replacement for my work iPad and am considering setting it up on a separate Apple ID, in part because it would relieve some iCloud storage issues with my iPhone 6 Plus and iPadad on the same account. And allow me to tie my work CC to that Apple ID. What am I giving up by putting them on separate Apple ID? It is convenient to use iMessage and Facetime on either my phone or iPad, but not sure it is that big a deal.
