It's amazing. I'm actually living in the future!
The makers of Tipp-Ex were probably devastated when I move to a word processor and no longer needed to buy in bulk.
The height of technology in the library I worked in was the microfiche. (For those too young to remember them, this is what Google looked like in the 1980s.)
They were cumbersome and always made me dizzy when I used it - the articles scrolled ridiculously fast unless you had a very steady hand.
And yet, now, if I have a query, I just type it into Google (other search engines are available!) and the answer is there, in my own home, without the need to changed out of my PJs or anything.
I admit, I really don't belong in this century - I'm constantly in awe at the minds that have come up with all of this stuff.
What great pieces of technology from the past do you miss?
Or, indeed, which pieces are you glad you don't have to use any more?
