Microsoft Co-Founder Hits Out at Gates

Even before Microsoft made him wealthy, it appeared to people who knew him that Mr. Allen had broader interests than running a software business. David Bunnell, who worked in New Mexico in the 1970s with Messrs. Allen and Gates at the pioneering PC maker Micro Instrumentation and Telemetry Systems, better known as MITS, said Mr. Allen was more passionate about music and culture than his business partner.

“He was more interested, in a broader sense, in the world,” Mr. Bunnell says. “I think Bill is more single-minded.”

Something tells me that THAT is exactly one of the most crucial things that distinguish people like Gates, who were able to create remarkable companies.
