Former Microsoft CEO Steve Ballmer doesn't use his Twitter account all that often; he has a curiously low return of just over 6,000 followers from 30 tweets. But when he does — true to form — things can get emotional. And today's no different: Ballmer weighed in on his former employer's torrent of announcements regarding Windows 10, which he thinks "rocks."

Although Ballmer probably wouldn't have made some of new CEO Satya Nadella's decisions, such as making Windows 10 a free upgrade for the majority of consumers, it's clear the man's love for Microsoft runs deep.
