Advantages/Pros of Unlimited Internet Access/Connection?

Question

What do you guys think are the advantages of unlimited internet access/connection? If possible, please list down the disadvantages too. Thanks for your time and effort.

Answer 1

You pay a flat fee, versus per minute fees
You don't need to dial up, you just turn your computer on
Connection is faster
Since your connection is brader you can use more online applications, like VoIP technologies, game servers, file transfers, etc.

The only disadvantage I see is if you don't use it, you still have to pay the flat fee.
