Thanks. I've tried other DEs and always came back to XFCE. xfeces, I call it jokingly, because it's got problems too, but I still like it.
Oh, I forgot to mention that you should look up Maxx Desktop, which is supposed to be a modern port of 4dwm from IRIX. I tried it as well, but I found it to be a clunkier experience than XFCE, although it looked much better.
It is very similar to Windows. All my Windows computers run on the classic interface and it's a setup that works very well for me, so even on UNIX-like systems i prefer that way of doing things. So my XFCE doesn't perfectly look like Solaris, or IRIX, but I tried to take some design elements and use them while keeping things the way I am used to.
I do like some newer things. I like 3d printers, I guess. I can't think of many new things that don't make the world worse, though.
