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.
Con No mobile installation
You cant install pure os on a android phone.
Con Slower updates
Updates are slower than an unmodified Debian.
