The Linux Foundation has posted a long and thorough two-part interview with Linux founder Linus Torvalds, part of the Foundation's "open voices" podcast. The first part of the interview focused on the Linux development community, while the second part sounds off on everything from patents and innovation to the future of Linux.
According to Torvalds the reason Linux hasn't taken off is that most people are happy with the way things are. "If you act differently from Windows, even if you act in some ways better, it doesn't matter; better is worse if it's different."
Torvalds also attributes much of the frustration with Windows Vista to this same reason. In other words, it's not that Vista is worse than XP, but it's different and that causes distress among users.
Torvalds thinks that since the basic uses of the desktop have been established, changing it in some radical way is more likely to alienate users than impress them.
The transcripts of part one and part two of the interview are available through Wired Blog.
