Not in the sense you describe, but my laptop is NEVER turned off and throughout the day, I am on and off using the internet, but that is because there are so many GOOD things to do. I love coming on here, because it feels like "home" and facebook and Yahoo Answers. I have a thought about something and then can do a quick search; soooo convenient.
I used to get upset if the internet doesn't work, but there was a period of time that I was not allowed to use the internet ( my fault) and at first, it was AWFUL and I seriously was hyperventilating. But after, say, 3 or 4 days, I quietened down and had to begrudging admit that I was getting a lot more things done than before and I began to appreciate the fact that I could not go online. I love reading and doing cross stitching. When I got the internet back ie my lappy, I almost cried and wished I was still banned, but I soon got back into it. What this has taught me is that I can do without it, if I have to. Also, I am not unrealistic to know that something could go badly wrong and there is no internet for some time and so, I make provisions in my head, of things I can do offline.
