An argument favor GNU/Linux

In Signposts of GNU/Linux Growth in 2007 Roy Schestowitz argues: GNU/Linux is extensively used in several different areas of computing. Besides its increasing popularity in desktop computing, the technology trends will make the role of GNU/Linux in supercomputing and mobile equipment more and more important. He writes:

" As time goes by, appliances might inherit the important role of traditional desktops. Mobile and ultra-mobile devices could gradually replace laptops and servers to become more predominant owing to Web-based software, which also moves storage toward the back end."

This argument implies an important massage: supercomputing and large-scale data warehouse
will dominate the future.
