As others have mentioned, it really depends on your use case. I use my phone as my primary camera, and my iPhone 6 is miles better than my iPhone 5. Although if you're not going to be taking advantage of any of the new features, then you're definitely not going to feel like a $700 phone is worth it. Then again, there's no point in even considering an upgrade to any device if your current phone is perfectly suitable.

Wouldn't investing that money in a 'real' camera be more ideal though?

I feel that most phones these days have pretty adequate cameras for their most common use-cases (Instagram, facebook, some holiday/party snaps, etc.).

For any other use-case a proper camera is the way to go in my opinion.

iPhone 5 and 6 have hardware and software features, like the 1000-gradient flash, that are unavailable on any other camera. It's one of the best point n shoot cameras on the market.

I have a decent DSLR, and I rarely use it because I rarely happen to carry it. Even when I had a Galaxy S, with a pretty poor camera, I was making much more use of the phone camera than I thought I ever would. The affordances for instant editing and posting are just a world apart on smartphones.
