I gave myself an extra day to explore Mobile World Congress, yet I still ended this year’s pilgrimage to Barcelona wishing I’d had more time to check out all the gadgets/services/apps on display. It appears I need to work on my MWC clock management.

3/3/2015: How Comcast, Verizon, and the Rest of Big Telecom Blew the Net-Neutrality Battle, Yahoo Tech

I’d had this column in mind since President Obama’s surprising switch to advocating a Title II reclassification of Internet providers as “common carrier” telecom services.

3/5/2015: 7 Things We Learned About the Future of Technology at MWC 2015, Yahoo Tech

I contributed a graf or three to this recap of the show. I also had a photo of mine show up in Jason Gilbert’s look back at MWC’s weirder sights.

3/8/2015: Is Apple Pay not NFC?, USA Today

Some grumpiness over press coverage treating Apple Pay as a species separate from NFC payments got me to start asking a few questions, leading to a column in which JetBlue PR essentially left some of its earlier statements inoperative.
