You must think the Tesla is non-thrilling because there are not yet ubiquitous charging stations.
You must think 4G handsets are non-thrilling because there is not yet enough 4G coverage.
You must think Thunderbolt is non-thrilling because there are not yet enough devices that support it.
To summarize, you think something is not "thrilling" because the world at large is not ready for it yet. This "keep doing what we've always done" approach really bugs me, and is not a good way to think if you have any interest in progressing and actually making anything better.
