It's kind of a shame the designs basically just kept being a refined iMac G5 style, the changes between G3->G4->G5 were really cool at the time (even if G4 is the best since you can actually adjust the height of the screen). I'm glad they at least brought some fun back to the iMac with the M1 colors.
I remember the G4 with great fondness; my dad's G4 was what I did homework and gamed on as a highschooler, and then when he retired it I brought it to college and it served as our living room 'jukebox' for another five years.
