"Mobile First!"  Why?  Because mobile is exploding; because mobile forces you to focus; and because mobile extends your capabilities. Take two minutes to watch the introduction of this Luke Wroblewski video.  Over the next few years, tablets will have a compound annual growth rate of 35%;  Smart phones will grow by 18% (Canalys).  Yrjö Neuvo, former Nokia CTO, predicts that by 2020, mobile users will be downloading one Gigabyte of content per day. But Wroblewski's message is about more than the growth of mobile technology.

"The Computer for 21st Century" does not have a keyboard or a monitor.  Ubiquitous computing is arriving as the Internet of Things (IoT), transparently embedded in everyday devices in your home and in your city.   M. Weiser from Xerox-PARC in 1991 envisioned "tabs" that we would always carry, now people live and sleep with their phones.  Data for connected devices will transform society at a scale even beyond the WWW.  All devices and the data they produce will come with a location using   GPS/GNSS and soon with ubiquitous indoor positioning.
