I agree. I am still using Mathematica 5 for Students, which I purchased when I was a student. Despite the fact that at the time I bought the version for Windows, it is worki g like a charm on my Linux laptop thanks to Wine.

Nowadays my daily workflow is mainly based on Python and Julia, I use Mathematica just for symbolic calculations (solving differentialequations, computing integrals...)

P.S. Once I had the chance to use Mathematica 12 on a server in my University, but I found that it offered nothing that I could need that wasn't already in version 5...
