Depends what you refer to when you say "need". Is internet a luxury? I want to video call my parents thousand of kilometers away (webcam). I want to do it without the connection being interrupted every second (good internet connection). I want to be able to distinguish my mother from my father (HD webcam) and hear them without buzzing sounds (good microphone). But wait! There's this thing called a "smartphone" that has good camera and microphone, and you don't have to be sitting in the dark corner where your PC is. The problem with ads is that most of the times they promote a product for a need that either doesn't exist or does not apply to you, but still, after being spammed a lot you might give in and think you actually need that.
