Mobile is the future
One of the many advantages of web applications (Software as a Service – SaaS applications are the best example here) is their “portability”. Before the rise of business web applications one had to tap in a corporate server using difficult to understand or use technologies like “remote desktop” etc., to gain access to corporate data and functionality. Then the World Wide Web came and new, reliable and safe (although many don’t believe so) applications saw the light of day. Tapping into the corporate environment became so much easier. Also, using a computer other than one’s own became possible (e.g. internet café, a friend’s house, borrowed during vacation etc.)
