Slowly but surely Linux is being chosen over Windows not only for servers, but also for desktops.

This is not at all surprising as Linux is the most popular Unix-type system.

There has also been an exploit for the Safari web browser, which makes it possible to launch a script and execute commands on the user's computer. It therefore seems clear that OS X may be fertile soil for security researchers.

Many major manufacturers have either already developed or (are) planning to offer devices with Linux. The only thing that is needed to encourage the evolution of Linux mobile is a critical mass of users.
