eMail, eFax, eGovernment, eElection, but also iTunes, iPhone, iMobile, etc. We’d say i represents the Internet, one step ahead of Electronics. Also i represents personality, humanness *heh* or I-ness.
But honestly, I always read e as transcendental, and i as imaginary. So, are you working in unexplainable and irrational projects, or imaginary ones? Or both 😀
