As a developer for a decent sized company, I can tell you that we looked into the Linux market but decided against it because it's just plain unprofitable. The fact is, there's no money to be made for companies such as ours on the Linux platform. However, with so many users on the Windows side, if only 5% of our users pay for our software, we've made our money back! Even if it's easier to develop for Linux or BeOS or whatever, it's just not worth the effort.
