I've two important question: 1- Why Ubuntu and also Kubuntu are downloadable in their simple mood? mean why they don't have additional softwares such as JAVA and WINE and Dictionary and etc. i know that we must download it from software center but it takes time and also cost. Internet isn't free and also all people don't have access to high speed Internet. Also so many times the software center's server is busy and we cannot download with high speed or even it gives error.
2- Consider that I've downloaded kubuntu and Installed all of my necessary softwares on it. how can I create an installation DVD to use it in the future when I want to reinstall Kubuntu (I wanna save time and cost to avoid re-download sotwares from Internet) and give this installation disk to my friends?
