The fortune 500 companies also need the large multinational corporation that supports the well tested and widely deployed legacy systems with bugs and more especially security fixes.

Deploying a completely new codebase and opening yourself up to a frightening array of bugs is not really an acceptable risk, sadly.

I do enjoy the OS postings too. I hope to see more interesting info on the BeOS ports like Haiku on here too. I also loved that I could finally mess around with RiscOS and Plan9 on a raspberry pi.
