Dell states: Ubuntu Linux is safer than Windows

The VAR guy spot one very interesting statement on Dell’s website.
By looking at Dell.com/ubuntu there’s a list of ten points why Ubuntu Linux is a great system.
At point 6 Dell shows its guts and write in plain black on white what follows:

I don’t know about you but I see a trend in Linux system adoption and diffusion which is getting more and more steep every year. Security is surely one of the best reasons why users should venture in adopting a Linux distribution as their computer system. While the fact that the vast majority of malware is written for MS Windows this is not at all the only reason why Linux systems are safer than Windows ones. There are strong architecture, environment and philosophy differences that make the security split between the these two systems look more like a rift.
