What do you think of tranquility tulinux starting from elementary school?

What do you think of tranquility tulinux starting from elementary school? -- Linux general technology-Linux technology and application information. For details, refer to the following section. I know that linux is an operating system, but I think it is similar to DOS. With the idea of playing, I bought a red flag at the stall (My nationalism is still very serious). The installation was not smooth, and it would not be used if it was well installed, but I thought it was a new world, very excited. I used linux.

If it is not the suggestion of two primary school and university teachers, if it is not an enthusiastic open-source community, I will still fight in the Registry and Kaspersky, and I am still searching for cracking software everywhere, I am still complacent about using adobe reader to read e-books. (really, a lot of friends have posted posts on Tianya forum asking how to open the PDF document ).

I use linux completely now, without any inconvenience, but I do not know much about linux.
