I hate them all. I am currently writing this from a LiveUSB of Ubuntu 11.10; this Unity crap is giving me fits. You know your friend’s little sister who is pretty but completely annoying and you wish she’d go away? Yeah. Like that.
You know how much you hate the Microsoft ribbon menu crap with stuff squiggling and moving around, stuff hidden in weird places? Yeah, like that, too.
Props to Mint for MATE, a fork of the Gnome 2.x line, back when desktops were still usable for things other than showing off to folks looking over your shoulder.
Is there any upside? Well, I don’t reject the application searchbox concept out of hand. It could be a useful popup.
I reject all these heavyweight, overdesigned, dumbed-down interfaces. I think the special effects in Minority Report corrupted the mobile interface, and now the mobile interface has infected the desktop. Fsck that. Openbox for the win. Linux is not for stupid people or those who are fascinated by shiny objects.
