Uncle Barton is a(n) laggard in the diffusion of the innovation process for telephones.
A laggard is a term that means a person that makes slow progress and falls behind others.
In the case above, Michaela found out that her uncle, Barton, was still renting a rotary-dial telephone. On top of that, he also had paid a lot in rental fees over the previous 30 years. Nowadays, people are not using rotary-dial telephones anymore. Instead, people typically use at least a handphone (if not a smartphone) to communicate with each other for the past ten years or so.
It shows that Uncle Barton falls behind others in terms of technology. He could have saved thousands of dollars if he switched to a more modern phone than a rotary-dial telephone.
