I have an even cheaper suggestion: doing like me, using org-mode for notes and small potatoes computation, Python for more complex stuff, rarely Maxima CAS, and LaTeX to produce documents. All these tools offer much bigger features set, much bigger flexibility, produce much better results and are FLOSS tools.<p>Seriously the MIT Missing Semester MUST be a high-schools mandatory course, anyone who want to have a non-mere-manual profession must have passed this course. We are in damn 2025, it's about time to recognize that computers are the mean of knowledge like papers and libraries before, not knowing how to use them properly means being illiterate, even with some PhDs.
