Techie is a term, derivative of the word technology, for a person that displays a great, quite possibly even obsessive, interest in technology, as well as high-tech devices, particularly computers.
Notably, techies express a disregard for any technology that could possibly be considered obsolete, even if the technology or process in question might only be considered obsolete within the techie community. Consequently, techies are also often early adopters.
With the increased spending power of techies, a few media outlets exist that cater solely to them, most notably Wired, Slashdot, and, while it existed, TechTV.
Techies are usually considered to be geeks or nerds, however the reverse is not necessarily true and more people who would not be considered "geeks" are becoming techies, especially with the advancement of technology in recent years.
