are those people who pay too much for something that doesn't quite work yet. They buy new, unproven products/technologies. They put up with all the production delays, bugs, defects, missing features, cryptic documentation, lack of third-party support, and risk that the product will never work right. They do this because (a) new stuff is cool, or (b) they think early adoption will lead to an advantage over competitors who are more conservative.

There is also the risk that a competitor can lure potential early adopters away with announcements of similar products (see VaporWare
