I've been internet free at home for just over a week, due to a house move where there is no phone line at present.
I'm finding that I have more time to do other jobs when there are no forums to read, or random Wikipedia entries to read and correct.
But also it's amazing how much you rely on the net, like bank accounts, bill payments etc. I'm having to fit all this into my breaks at work - like now.
There is a point to the story though, as access to the internet in a largely unfiltered format (ie not in China) gives the users access to a wealth of knowledge, like basic health information. Stuff they would have to walk miles to the city library to access previously.
Did you watch Dr Aleks Krotoski's recent BBC2 program The Virtual Revolution? She covered stuff like this in the first program...
