My second big work event of the year was in Barcelona for Mobile World Congress (MWC), the biggest event dedicated to the mobile phone and cellular industry. I have never been to the event before, and it has certainly been on the list for a long time. This was the 20th anniversary of the event being in Barcelona, and any excuse is a good excuse to spend time in that fabulous city. I had a little bit of time to explore, but mainly it was full days in the conference center.
