Of no use to bling desktop users who like their desktop cluttered with files/folders but for anyone who wants a minimal very functional desktop, these are well worth a look. I
am was a big KDE user (15 years ) but had a look at Crunchbang a while back which uses Openbox as it's window manager, after a few weeks playing with it's config got a very nice desktop, none of that cluttering geeky conkey setup but after trying a few panels ended up with fbpanel. A simple but very functional desktop for any computer. I then started looking at tiling window managers but they are a bit geeky and have their fanboys however I really liked i3
http://i3wm.org/ and posted a couple of times on their mailing lists and got replies within minutes.i3 allows all the options, stacked,tiling , tabbed and floating all with a couple of keys, after years of using computers it is like a breath of fresh air, great with either twin screen or tiny screen. well worth looking at.
