I am a Virtual Marketing Specialist and liked 'power user' until I stumbled upon this definition on techterms.com "When it comes to computers, there are regular users and there are power users. Power users, however, require top-of-the-line machines that are optimized for their work purposes. Power users include video-editing professionals, high-end graphic designers, audio producers, and those who use their computers for scientific research. Professional gamers (yes, there is such a thing) also fall under this category. These users seek the latest and greatest systems because no computer is really "fast enough" to suit their needs.
I definitely do not consider myself a regular user, so what is a term in the middle?
