Yes, internet has taken a part of our way of life. For many jobs (your enterprise looks more serious if it has a website, or to communicate, to buy/sell, etc) but even with the studies, you have some documents that you can only take on the univerty's website (if you can't, there are computers with internet at the university).
And there are even some things weird like this one : if you want to get internet, or if you have a problem with your internet installation, you have to go on internet.
real life-experience : "Yes, Hello, internet doesn't work at home, what should I do ?
-Check on our website..."
Internet is like a new territory. It is the creation of a new land, where the rules are different, often without any border (well, "often", indeed, because some pages are limited to a territory).
It's not "come in my office", it's rather "come on my website".
But we can't live in this territory, so... it is not so important for our life, it is just very useful nowadays.
