From the article:
"There simply aren't enough Linux users today to put much pressure on hardware and software manufacturers," said Raymond. "To attract more users, Linux must support the popular drivers and file types in use today. Freespire is the one distribution I see willing to make this unfortunate but necessary compromise, so I'm happy to contribute to their effort."
"Raymond believes desktop Linux is entering into a critical period, noting that historically, users have shifted operating systems during periods of fundamental changes in hardware platforms. He believes the PC vendors' embrace of 64-bit computing will provide desktop Linux a unique window of opportunity, which if missed, may not come along again for many years.
