I would have to say I have two particular favorites at the moment: XFCE and Enlightenment (E17) environments. Both are lightweight and allow the user to do as much, or as little, customization that they want to. I currently run Xubuntu, which is considered the best XFCE-based distribution, and I could not agree more. The fact that it is so lightweight on my system is amazing. Currently, with Chrome and gMusicBrowser up, the highest CPU peak has been roughly 28% and memory usage is at 505MB of 1,759MB! I have not used the E17 environment a lot, but I have tinkered around on it through the Bodhi distribution and a few others. If you install this environment along with another, it is completely bare, allowing you to do the full customization. This may or may not be good for users as it all depends on their knowledge. I am surprised this has not been discussed a lot! Linux Forum has been getting a lot of new members, so I wanted to hear some opinions regarding your choice when it comes to a desktop environment. What do you like? Why? If you are new to Linux, you just might find some good hints as to what you can try out first.
