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.
TBF, before win95 there was definitely legit software that you could buy (not download) that would compress memory, amongst other tricks, to effectively give you more RAM.
I was thinking and nothing was to big a deal but you are right. ssd and before that optical mice were major upgrades relative to price (price being the factor when I finally bought them.)
