I'm looking for an expression to use about a recent technology, where there are some uses already, but there may be more not yet widely known, and people are still figuring out what to use it for. I would like to say for example
It's been 3 years since smartwatches came out, but [there are more possibilities in them that can be leveraged that people don't know about]"
meaning that there is a new use coming up which I'm going to talk about. What I would like to express is that there is something more in them, that has not been leveraged so far, but is about to be.
I know about "more than meets the eye", but I'm looking for something that refers more specifically to a new way that something can be used in.

...but we are only beginning to scratch the surface of their amazing potential.
If you wish, you can change 'amazing' to 'incredible,' 'unlimited,' or another sensational adjective of your choosing.
