The following video is part of our "Motley Fool Conversations" series, in which industrials editor/analyst Isaac Pino and research analyst Lyons George discuss topics across the investing world.

Apple is truly leading the technology revolution right now, as the largest company in the world with the most consumer-centric products. Sometimes it's easy to forget the other innovative companies operating behind the scenes.

IBM is a prime example. Under the leadership of Sam Palmisano, IBM transformed itself and is currently innovating in a primarily untapped market of creating NASA-like control centers for the largest cities in the world. So, the company that cut its teeth making tabulating machines 100 years ago is now blazing a new trail in "smart cities." Isaac thinks this Buffett stock still has significant room for growth.
