Personally, I would like to see miniaturization become the the trend again.
I haven't been interested in a new release since phablets became the standard. I don't need my phone to replace my PC. It just needs to be able to run a web-search in a pinch.
I was really hoping the Apple Watch was going to be the next leap forward, but they were very careful about making sure most people didn't replace their phones with them.
I don't object to them as an optional feature, but they are about as useful as optical drives to the typical user.
