If you are old enough to have reached adulthood before it really became a household thing?
I love the net, I can't tell a lie! But there are some things I really miss from 'before'.
Such as:
The simplicity, from booking a holiday to clothes shopping, and when watching the news only once a day was normal. Feeling satisfied with a quiet hour in the library researching, and not having a device between you and the world perpetually.
I miss how slow fashion felt, how there was less pressure to 'do all the things'.
I miss that weird, organic way of finding things out for yourself.
I miss how slower paced things felt.
I miss how not being able to find data on everything actually made life seem less stressful. You weren't dizzy with indecision over which hairdryer to buy 
There was less info, less choice, and less access to global affairs in general, but whether this has improved life or not I really don't know. But it's here now, and there is much to love about it, as well as to criticise.
Anyone else?
