I remember going to a trade show in London in 2001 called &quot;m-Commerce World&quot;, which was all about the impending revolution in mobile transactions and payments.<p>At the time I worked for a web development company that identified itself as an &quot;e-business solutions agency&quot;. It was in the process of collapse following the dotcom bust, and we were looking out for any new opportunities to cling to. I remember feeling a bit second-rate at this trade show when I introduced the company I worked for, because we were only &quot;e-business&quot; while the exhibitors were very proud of being &quot;m-&quot;.<p>Nothing came of any of it of course.
