Откуда есть пошла «i» в названиях техники Apple:

Steve had a name in his head for the iMac that made us all shutter when we heard it. He thought that MacMan would be a good name... It's pretty terrible name. He just liked it. He couldn't really explain it. But he did what he often did, which was «I challenge you. Do something better». The concept of that first computer was that it was the easy way to the internet. So, «i» for «internet», and «Mac» for «Macintosh». It was rather obvious to me.

Отсюда.
