Con Slow development
Con Software a bit slower to launch than for other distributions
Con Forums are not very friendly
Con There is often a black screen after update
Con An upgrade breaks the system quite often
Con Not much software
There is not much software available.
Con No USB Image writer
Con The default desktop environment is not very customizable
Maybe because it's a relatively new project still in its infancy and this may be fixed in the future, but Budgie is not very customizable. You can only change the theme and wallpaper.
Con Based on an old distro
DouDou Linux is based on Debian 5, which is pretty old. So this means the software found in the distribution will be old. This also means the hardware support will be lacking compared to newer based distros. So for those that do want to install it would be a good idea to make sure the hardware is supported by Debian 5 and DouDou Linux.
