What's with the "i"

Remember that in the 1990s the whole world started to use the prefix –e? E-government, e-learning, e-mail, e-universities, etc. At least it was clear then what it stood for: electronic. But why does everything nowadays get the prefix i-? After Apple’s iPod, iTunes, iPhoto, iLife, iWork and after iMode and iBridge, there is now a conference called i2010. So what does the "i" stand for? Information, investment, inclusion, innovation, international, inc., interaction, individualisation..? Or does "i" just stand for "I"?
