Why do you then think that Google and NASA have invested in a D-Wave computer[1]?
From what I read, D-Wave computers seem to perform better as the difficulty of a problem rises.
I'm asking a genuine question here; I'm not much aware about the whole D-Wave and Quantum computer thing.
Honest question; I used fluxbox for some time. As a minimalist I loved it in the beginning. But, as soon as I started using it for developing/coding I did not find it intuitive at all. I, especially, found it hard to manage multiple windows.
Now I'm on Gnome and the combination of plank and the panel makes it amazing to work on.
I'm relatively new to Linux and installed fluxbox over Mint 14. Also, I don't exclusively use the terminal.
