What tool, device, or software that you used a lot, but then disappeared from your life (or from the world), do you miss the most? 
@Em0nM4stodon Norton Commander
@Em0nM4stodon
Portable minidisc players 😔
@Em0nM4stodon like early Pandora. For some reason, some of the best music was introduced to me then (2002/3, maybe?).
@Em0nM4stodon MacOS that did not take up much RAM, followed Apple's Human Interface Guidelines, and was stable.
Second is MacSpeech Dictate.
@Em0nM4stodon IRC gaming and programming communities. There are still remnants, at least for the latter, but it's not the same as it used to be 🥲
@Em0nM4stodon Compuserve CB Simulator channels
@Em0nM4stodon Macromedia Fireworks.
It didn't quite disappear, I still have it on an old laptop, but I can't update the OS without losing use of the software. But it's been years since I've used it, just lamenting really.
@Em0nM4stodon Regardless of the search engine, I really miss the ability to get online and search for anything you want an answer to and actually get that answer. Instead, I generally get the opposite of what I'm looking for with sponsored links, ai crap and answers that simply don't match the search criteria. Using double negatives and reverse search criteria can be amusing sometimes but quite seriously, asking the question here and waiting a day or two is often quicker and more useful.
I also miss being able to talk to people in person without endless reasons not to use antisocial meeeja messaging apps first. However, when you do get to meet these people, they end up being over animated, hand waving, shoulder shrugging, face pulling, anger filled, clones of everything that's wrong with antisocial meeeja. Can we have real life respect and decency back please?
Okay I know these aren't technically on the list of stuff you asked about Em but I miss these more than almost anything.
@RosePuckey That's a very valid feeling, Rose. I miss these too 
@Em0nM4stodon The iPod and my hand-curated music library. Spotify was a revelation back then but at least for me it has destroyed much of what was deliberate and intentional about my music consumption.
I cancelled Spotify about a year ago and want to either do a small iPod refurbishing project and put Rockbox on it or just get into vinyl.
@mellifluousbox @Em0nM4stodon Never really use Spotify for this reason. Everyone tells me I'm old school using loads of MP3s and Poweramp on an old phone (no sim just a Bluetooth connection to car or earbuds) as an MP3 player. Old school maybe but I listen to what I want to hear and add stuff as I hear recommendations usually here.
@mellifluousbox Same, only offline music from Bandcamp for me now. It makes me cherish and care for my music collection so much more.
@Em0nM4stodon pretty nostalgic for my VCR honestly
I get an urge to rewind every time the end credits roll
@Em0nM4stodon grooveshark because I could create playlist on the fly and I dearly miss the feature.
@Em0nM4stodon
might be Zope.. or <Table>Art .. dunno (from my life)
