The C64 wasn&#x27;t the best platform for running a GUI, and GEOS required a great deal of patience.  I eventually went back to non-GEOS tools for most things (Word Writer 4, yay).  GEOS was nonetheless an impressive technical accomplishment.  It was amazing to see the sophistication delta between software from the early days of C64 (e.g., those educational programs ported from PET) to what was available towards the end on the exact same hardware.
