Simplicity vs Schwab's Robo Portfolio

Nearly three years ago, Schwab launched its free robo Intelligent Portfolio and today has over $25 billion in assets. Schwab did not disclose what was in it, so I bought one in order to write about it. I was somewhat critical in my personal look at the Schwab Intelligent Portfolio as well as a follow-up revisit of Schwab months later. Though there have been some changes, it's still a 16-fund sophisticated portfolio.
