I don't miss dial-up internet, I just don't. I don't even like the sound because it's just digital screeches and it's a sound that makes me cringe a little upon hearing it. Because I remember the times when I'd be listening to music with headphones with volume high and then that fucking digital screech just blares into my ears.
I don't miss waiting 30 minutes to load a page. I don't miss a bit of it.
Netbooks. Jfc that performance of a mid-tier smartphone whereby they'd become unusable in a few years for anything heavier than lxqt or some tiling wm, a simple music player like audacious, vim and static websites (accessed only using something lightweight like Netsurf, Badwolf or Palemoon as well). I don't remember what happened to mine but I'm pretty sure that even mpv with no scripts would drop frames like crazy on FHD x265 matroska videos. I'm so glad that ultrabooks started to become more affordable and nowadays I'd be able to buy an i7 t440s for the price of my acer aspire one back in 2011.
I don't miss them either, but they were necessary in moving our portable devices forward. Everyone and their best friend was making bigger and faster laptops. No one was making power efficient and light ones. Netbooks filled that need. And cost less than a macbook air by a large margin.
I used an Acer one with an atom as a mobile terminal for six years before the battery gave up on me. I was getting a day's work out of a device I could fit in my (oversized) back pockets. And since it was just an SSH device, the speed didn't matter.
Also, synthetic cannabinoids. So glad that kids these days are not exposed to this shit, but I wouldn't say I'm happy either with all the fent out there.
