Arguing about the niceties of the UI is all well and good but the actually problem is far more fundamental. What killed the linux desktop? Drivers. Mostly graphics drivers but some others as well. Who cares if the UI isn't ideal if the damn thing can't sleep and wake up properly, or if it spazs out every time I plug in an external monitor.
When have you last used Linux? Drivers haven't been an issue anymore for years now. I don't actually see any problems with Linux. It's just not meant to be.
I'm sure you'll blame this on AMD's drivers or shoot out some other random technical reason. While i understand the technical issues, I just don't care, I have far better things to do than care about this shit. It flat out doesn't work and I don't care why.
