hi. i'm not too knowledgeable when it comes to computers. although i've been wondering about linux for a long while, i didn't download anything because i had so many questions. i hope it's ok to put a short list of those questions in one post. anyway, here goes:1. how does linux differ from other os like windows?2. do i need to delete windows to use linux?3. how is linux (and ubuntu) better than other os?4. is linux not for people who are computer illiterate?5. what comes with "ubuntu"? is it more a browser or an os?6. what is there in terms of add-ons? or downloading cd software?ok, i'll stop here. i'm looking forward to learning more!
