The internet connected computer in the home was a productivity tool. Even just gaming required gamers to become pretty PC/OS/tech savvy. Cheap postpaid internet phones are bread and circuses. They two have different effects on society.
Not even all geeks had it.
So by the time smart phones hit almost everyone had a computer at home. If you are talking about the 90s that isn't relevant, the relevant part is how smart phones changed things, and at that time internet was already available to a large majority at home, smart phones just made it portable.
50% households in US had computer at home. 36% had internet access.
I love when people reply wuth shit they have no fucking idea.
