C|Net is carrying an interview with Sterling Ball, CEO of Ernie Ball, one of the leading guitar manufacturers in the world. A couple years ago, Ernia Ball made headlines by being one of the first major companies to completely switch away from Microsoft, focusing mostly on Linux and other free software.
This interview discusses what caused them to switch, how they've faired, and some of his thoughts on the future.
I want to mention that this interview is quite educational (you rarely hear a CEO speak this way), and definitely worth taking the time to read.
Here's the full interview.
