Talk to the hand! Analogue Aesthetics made this one off microphone that can actually be hooked up and used via a minijack plug. If this could be wireless, how awesome would that be? With everything getting smaller, it's only a matter of time until that happens.
Implications - Tech-based companies are definitely living up to the expectations of consumers who want small things that pack a punch. With technology advancing everyday, it appears that products are getting smaller and more efficient for convenience. It's likely that things like microphones and MP3s will become smaller than they already are, yet even more advanced in the future.
