True, no problem if you use both. But Linux has one massive flaw: it is extremely difficult to use. Before you jump in, listen to this: using MacOS or Windows, I can do practically everything graphically. No command line required. In Linux, I am cursed by the GNU public license. Some programs I have to compile before I even use them!

The Linux kernel is great. But crashy Window managers like KDE are not. I put Mandrake on my system at school (for a project about JSP) and home. KDE crashed nearly every time I started the machine.
