Card catalogs! Oh man, I remember those! I think they finally started disappearing towards my later years in high school... (I'm almost 26)
I can relate to most of the stuff in that thread. Makes me feel really old, especially when there's people responding they don't know what some of the stuff is!
Like others posted, I still shoot film, though! And develop it myself and make my own prints
It's definitely a dying art, but makes you appreciate photography a lot more... I get a lot more excited over a good picture I took on film than ones I take on digital.
The car door one is good, too! I forgot how spoiled I've became with remote door locks, and then this summer I bought a '94 Toyota Supra and had to train myself to press the lock button before getting out of the car. And writing checks! I bet nearly everyone can relate to be absolutely annoyed when someone in a check out line starts to write a check nowadays! And to think only 3-4 years ago I didn't have a debit card and wrote checks for everything, and actually paid my credit card through the mail! Oh the horror!
