Fab.com 36-year-old Co-founder and Chief Design Officer Bradford Shellhammer is savvy enough to carry an iPhone 5 wrapped in a blue leather Prada case.

He reports his favorite app is Mail and treats his inbox like a to-do list, keeping below 15 items at all times. He also does not like to use his phone for either texting or calls. "Calls annoy me; texts I always miss. I am an e-mailer."
