A common part of the conversation about Millenials is to describe them as exceptionally technologically-savvy; some have called them "digital natives." But research does not bear this out; people of older generations can be equally tech-savvy, and while many Millenials love their phones and social media, etc., the reality is that all of us are acculturated into a particular era of technology, and members of each generation can exhibit a range of comfort and skill working with different technologies.
