Welcome to broadband. It's a little like stereo; if you never heard it you'd never miss it; once you've had it you can't do without it. (a 12 step program is in the works).
Our broadband connection has allowed us to:
1. not get frustrated with arbitrary disconnects
2. throw out our fax machine and all it's attendent foibles
3. change the way we do business
4. Talk with someone, while accessing a website or two while sending/receiving a fax document and sending an email, all on one phone line. (You'd have to be as old as me to know how amazing that all sounds)
5. Use Instant messenging (aol/icq whichever) while doing all this other stuff.
If you can actually carry on a phone conversation while sending a fax, receiving an email and instant messaging a friend; while also handling a call on the cel, you are truly a 21st century person.
