You can have the best of both worlds, you don't need to go without either a GUI or a CLI.
On my desktop(s), I have both GUI and CLI applications, both ready for immediate use. Ferinstance, I have a GUI browser as well as several CLI xterms.
In fact, I probably do much more minute-to-minute work using the xterm CLIs, but that browser is always available for reference work (and entertainment!).
