With the hundreds of distros that are out there, I figured this would be a good place to start a discussion to truly help the new users decide on a distro to use.
I would like as many people as possible to outline the Pros, Cons, included Desktop Managers, intended users and your personal feelings toward distros that you currently use or have used, please make sure to note the first and last version numbers of the distros you used so people know if your input may be out-of-date, noobish or highly experienced. Also, please feel free to attach screen-shots of your desktop, because the appearance may be important to some users.
I thank you all in advance for your cooperation and input.;)
Please do not try to turn this into a flame war, each person is asked to state their opinions of various distros, if bickering and arguments start they will be cleaned or removed to preserve the informative nature of this thread.
