Man, E17 is very cool. I am just trying it for the first time.
Unfortunately, its dev team is so small that I do not know if it will ever see a non-beta version. It reminds me of driving a convertible. A lot of fu, but do I really want it as my main workhorse? Sad, because they do something genuinely different, and do it very well. I almost wish the Gnome devs would have a look and see different done right. With some more resources this could very well be the choice of Linux desktops....
