My family's first computer in the 80s was an Amstrad PC1512 (an IBM XT clone). We received 4 nice colorful system floppies with it, and it included a GEM Desktop. I remember sometimes logging into GEM, because it looked awesome, but we never had a single program to run on it, so it was practically useless. https://www.youtube.com/watch?v=DlUTzydzLVI
