First, $80 000 for a Memplicator™ may be somewhat expensive for an individual, but it is cheap for most organizations. Furthermore, there is no claim of any limitation regarding how many times you can use it, so you have a big return on interest here.
One consideration : how many memories one human can manage is limited, but let's consider you have enough space to ingest some extra stuff.
Scientists would welcome this. You could ingest the knowledge of other experts, and some would be happy to share it, especially those reaching their end of life: you have nothing to hide when you're about to die. So young people with lots of cognitive capacity would also benefit from experience and memories from other. You can expect some boost in most science areas. No labs would miss such opportunity.
Investigators may find it useful to know what their suspects have in mind, but they will have to deal with lawyers and civil rights defenders: your memories are quite a private thing. The right to keep silent exists, so the right to hide your memory is likely to be enforced.
If you can copy memory, you can probably also store it and separate it into specific knowledge. So you could basically purchase any information and store it in your mind. You could instantly learn Chinese, math, coding, etc. Depending how memory works, this could extend to practice as well. If not, the value of manual practice and skill will become more important : your tailor will earn more than a financial expert.
You could also use it to build memories of travels, leisure, etc. By only remembering the positive moments of something, people would find it more interesting that the discomfort of airplanes, logistic issues, etc. Only remember the best part of great experience. It would maybe replace drug usage, or even become a drug itself, with people addict to intense memories.
If it goes mass market, people may also get used to ingest other people's unusual/weird memories : fantasies would become commonly remembered by more and more people, and people could end up less guilty about them. This could lead to more open sexuality.
You should not need lots of marketing to sell the Memplicator™ :)
