" Gates’s implicit criticism of Gmail was that it was wasteful in its means of storing each email. Despite his currency with cutting-edge technologies, his mentality was anchored in the old paradigm of storage being a commodity that must be conserved. He had written his first programs under a brutal imperative for brevity. And Microsoft’s web-based email service reflected that parsimony. The young people at Google had no such mental barriers. "
