If you have computer at home then your life seems complete, you can communicate with your family abroad, you can earn money by blogging or any online advertisements or selling your product online, you can finish your education through Internet and by computer you can all obtain this computer magic.
I cannot really say that computer is part of human's life now. But without computer life seems incomplete because people get used to it, its just how technology works. Sounds freaking but that is true. I myself admit that way, I am depending more on computer helps now specially that I have my little Sarah. It makes life easier!
