I'm a long-time Mac user. I have a MBP and I use it mainly for Logic Pro. I'm thinking of getting an iPhone just because I need a cell phone and I assume there must be some benefits to having an iPhone when you have a Mac. I found a used, unlocked iPhone 7 with 32GB for $450, an iPhone 6 64GB for $333, and I'm sure there are other options out there on Amazon. I don't know what the advantages of the 7 are, but double the GB and a lower price make me lean towards the 6. The phone I'm coming from is really bottom of the line so anything I get will be a big upgrade. Can anyone tell me whether I should invest in a newer iPhone, invest in extra GB, and what will be the benefits to having one in the first place?
