When it comes to the tech you carry every day, such as phones, tablets, and smartwatches, no show looms larger than Mobile World Congress. Tech giants like Samsung, LG, and Sony descend on Barcelona every March to show off their hottest new toys. And if you’re in the market, you’ll find new products that make the gear introduced just months ago look ancient. This year was no exception. A spate of powerful new smartphones, super-thin tablets, and swanky smartwatches you’ll finally want to wear has made it one of the most exciting shows in recent memory.
