Once again it's time to buy gifts for the gadget nerd on your list. And, once again I'm here to offer sage advice to prevent you from getting him or her the totally, completely wrong thing.
As I mentioned last year, picking a gift for a nerd without guidance is about as safe as juggling flaming chainsaws drunk.
This year, computer, tablet and smartphone ports have gotten more confusing. Does your lovable nerd have a phone with a headphone jack or just a Lightning port? Does her laptop have USB-3 or USB C ports? Does that same laptop have HDMI, mini displayport or Thunderbolt output to a TV or monitor? Choose wisely.
