I still have my G4 tower... mostly because it is too heavy to get rid of
I still have one too. It was pretty to look at but probably the worst new Mac I've ever owned. Within a year it was obnoxiously loud and pretty much obsoleted after just a couple years.
In contrast, I bought a new "Late `09 Mac Mini that I just replaced with a used late 2014 Mac mini about 2 months ago. That `09 was a real workhorse for a lot of years.
The `14 only cost me $330 at OWC with 16GB RAM and is running the latest versions of the software I use and the only software I needed to pay for an update was BBEdit, and that only cost me around $35. I think I paid around $1200 for that G4 "Silver Door" tower.
