When I was managing an HVAC wholesale branch back in the early 2000s I used to be able to connect to my business' computer system from home to do orders. That's was back when cable modems were in their infancy and I was one of the first customers in that area to use one. It was SOOOO fast for the day.
Today's capabilities aside, just the possibility of being able to do things like that was amazing. Something that really opened up a whole new world for businesses and such. To be able to electronically connect and send/receive data? Who'da thunk?
