That brought nice memories of having my Casio Data Bank in the 80s and feeling like the coolest kid in school. It looked so futuristic and slick :) I remember spending quite a bit some time entering the phone numbers of my friends and relatives.
I had been using LaTeX for 25 years. I gave it a try recently to write a technical paper and I was blown away. I saved so much time. The immediate feedback and the advanced features were impressive. I had to include a budget proposal in one of the chapters and I was able to create a quick script that read a csv file with the different concepts and costs. I would modify the contents of the csv file and the document would update right away. I didn't have to recompile the document as I used to do with LaTeX... the results were there, right away, beautifully formatted. I am very impressed and will definitely consider doing more work with Typst.
