I love the Internet. I don't know what I'd do without it!
If it weren't for the Internet, I wouldn't have the DVD collection I have now, with some hard-to-find DVDs that I could only order online. I would never have finished my Transformers, NES, or Super NES collections to my satisfaction, or found message boards and websites for everything I've ever been interested in -- from action cartoons to the unexplained (ghosts, etc.) to 80's humor to like-minded people who love the same TV shows and movies I do. I even own CDs of a lot of music (video game soundtracks, for example) and rare posters that I'd never have found on store shelves in a regular retail store.
The Internet helps me keep in touch with my friends and family in different cities with ease, through e-mail and instant messenging. The importance of this was even more prounced when I had to spend a couple of years living in a small town due to my job. The Internet saved my sanity at that time!
Also, as an information & statistics junkie, the Internet is heaven on Earth for me. I love being able to research literally anything on the Internet, from math and science to sports history and a literary interpretation of Batman and Joker's relationship. You name it, it's on the Internet, somewhere! (Just try doing Google searches for random things that pop into your mind. You'll be surprised, trust me!)
Of course, the Internet was never meant to replace getting together with people in person, any more than TV was meant to replace reading*, or the car meant to replace walking. It supplements your social life if used correctly, not takes away from it.
*I read a study last year that said that students' reading, writing, and analysis skills improved if they used the Internet on a regular basis...
