"I'm not ashamed to say I'm a geek at heart." No, that wasn't Jared Leto talking, but Shaquille O'Neal. The retired NBA champion said it earlier this year when he was on a SXSW panel talking about his love of wearable tech.
He spends $1,000 a week on apps, buys 50 iPhones at a time, invests in little tech companies like Google (pre-IPO!), and developed his own video game, Shaq-Fu: A Legend Reborn.
He's also managed to receive a doctoral degree from Barry University in Human Resource Development and an MBA through University of Phoenix.
