Pretty much in a similar case to yours. I started playing with Photoshop with a 5.0 license my dad bought back around 1998, and used that same version for years. I pretty much still use the same features I did back then, and to me all those modern versions makes no difference to my workflow whatsoever. With time I just learned to do things a bit more efficiently like to use adjustment layers instead of destructive transformations, etc. That same 5.0 version would probably still meet the majority of what I would do with Photoshop.
