Hello all, I have a MBP and Mini Sever both running (pre-loaded) OS X 10.7.5, which I'm preparing to upgrade and I'm also considering buying my first iPhone. For the very purpose of NOT having any of my devices speak to each other and/or share any files, etc., I use each device for different things. I use hard-wired Mini for online financials i.e. purchases, banking, etc. I use my MBP for daily web surfing, email, social media, streaming TV & movies, and I use my phone to call/text, web surf, take/view recreational pics and videos. I've never created an Apple ID, never used iCloud, Mac app store nor iTunes store. That said, I need an Apple ID, now. What are the pros & cons of creating unique Apple IDs, for each device vs. one Apple ID for all devices? Thanks!
