Upgrading my computer’s primary storage from a hard disk (HDD) to a solid state drive (SSD). Really young folks on here have no idea how amazing it was for computers to go from taking minutes to start up to taking seconds.
Buying my first cell phone, which was a Nokia smartphone, in 2003. Having email and useful applications in my pocket, including maps and web search.
I feel like the sheer jump in performance from throwing an SSD into an old system was akin to what people would have expected from the “download more ram” scam ads of the 00s.
GPS was life-changing. (Yes, I am that old.) It used to be necessary to find printed maps of wherever you were going, which wasn’t always easy. Then you had to figure out a route. The hardest part was often the last bit of the trip, since you weren’t likely to have a detailed map of your destination city. An if you got lost, figuring out where you were was sometimes quite difficult.
People tend to think of it as mostly affecting longer trips, but finding new addresses in a city was at least as much of an issue. When I lived in the bay area I had a Thomas guide that was 3/4" of an inch thick, just for finding my way around town.
