Originally, i was really against the idea of a dark theme, and maybe i'd still prefer it if Ubuntu would lighten up a little. I understand the organic theme completely, but please...this is an operating system. Anyways, all the dark themes i had seen really turned me off and even the best ones seemed to be loved by some and hated by others. If we're going to have a dark theme, lets have one that we can all agree on. When i saw the Intrepid alpha screenshot, like many others, i gagged a little.
How people interact with their computer is really essential to their satisfaction. This is why aside from features, the software's stability (minimizing annoying bugs), speed (clean code and making everything as efficient and responsive as possible), and interface (look and feel) are the three most important things that should be our focus and be kept at a high priority.
We should really work to increase usability: http://mpt.net.nz/archive/2008/08/01/free-software-usability
I have looked through all the artwork submissions for Intrepid, and of all of them, this is the one dark theme that i would actually like to use: https://wiki.ubuntu.com/Artwork/Incoming/Intrepid/Wall-light
I first saw it on this Digg submission: http://digg.com/linux_unix/Intrepid_Ibex_Mockup_Designs
Of course, i'm sure everyone will have input to make it even better. This isn't a final design, but vote for the concept so far!
P.S. Please Digg :) Thanks http://digg.com/linux_unix/Vote_for_a_beautiful_usable_Ubuntu
