Opera back in 2000s.
Compressing webpages, built in mail, built in BitTorrent client, tab stacking, “fit to width” which would remove horizontal scrollbars, page tiling, mouse gestures, rocker gestures, I think it even had a calendar.
It’s a shame the direction Opera took after Jon left, but thankfully he started Vivaldi which feels like the spiritual successor.
VisiCalc
Dr Sbaitso early TTS and kinda-AI psychologist, with his cantankerous, all-caps responses.
Now that is a name I haven’t heard in a long time! There are videos of Dr. Sbaitso usage on YouTube (of course). Also got this software with a Soundblaster card somewhen in the 90s.
Dr. Sbaitso popped in my head and I had to see if anyone here remembered it. I had the privilege of being able to use it when it came out. Fun times!
You can still use it through the Classic Reloaded site!
