I admire the attempt at consistency with the K everywhere. Well, sort of. The commentary below doesn't apply to necessarily to this specific release or grouping of work. I also concede that it's time spent and in some cases money. Further, I admit that many will actually like it.
I'm probably not one of them. I order regular coffee and have it black. I don't get the Frappe/Crape or whatever stuff gets put in.
But really, I'm getting older. I don't want to learn someone's new paradigm for user interfaces. I don't care if it looks like Windows with enhancements. Sue me for liking some things about Windows. At least they were consistent. I like that release after release, the same Window D command brings me to the desktop (I don't know about Win 8).
Coming up with new "skins", tabs just irritates me. What I really want is a windowing system that's fast, and doesn't get in my way. When I tell it to go to the desktop, I want it NOW, and not spend time thrashing the hard drive trying to get to it. Same thing with the run command. Really, I don't need all these things as a user. Dammit stop it already. If you're working on KDE trying to change everything again for the 15th time in hopes that the world will all switch over to Linux and your own flavor of windowing manager, just give up. Let it be. Use your developer talents on something that really improves computing for people. Make the computer do something it hasn't before.
In case you're wondering, I run Ubuntu at home and use Windows at work. I just try to make everything come as close to the old "Start Me Up" Windows paradigm. Yes, it's old. But so was the song even when Bill Gates used it for Win 95. Just because something is old does not mean it should be replaced. There should be a reason, and, unless this is for the sake of art, that reason should be practical or at least logical.
I still want to continue using Linux along with a decent window manager, though mostly for the command line capabilities. I just don't want to learn something new unless it's going to give me more time away from the computer.
