Pretty is a feature, but ugly is subjective
I have a problem, and I admit it. Every time someone whines — and yes, I’m using the word “whine” deliberately — about the graphical design in Ubuntu, I tune them out.
To me, complaining — and yes, I’m using the word “complain” deliberately — about the default desktop is pointless. To me, this thread is proof. And this one. And any others like that.
Fact is, one of the first things people do when they install a system is to change the way it looks. Even if the default was a gift straight from heaven, one of us — probably me, actually — would immediately change it. And an ugly one — even one that’s ugly to you and me — gets changed even quicker. I can vouch for that personally.
