Linux will rule over Windows oneday. Its rate of development is faster than that of Windows. I was amazed when I could play my DivX videos in a 8mb Video Card under Linux with no probs. Linux runs better than Windows under low grade computers. I know how it is impossible to enjoy a DivX movie under Windows with 8mb of Video RAM.
*Pretty much off topic as one could think*
But that's the fast I just mentioned, which wasn't important enough to start a new topic to say that
One the other side, as a Home User, I am forced to say that: installing programs etc. in Linux is hard than in Windows. The main reason is why, there is not much self-installing packages that runs under Linux yet. (But soon in the future, I hope they will). Plug'n'Play capability is also another issue.
