Linus Torvalds, the inventor of the Linux kernel, has an absolute disdain for mobile phones. All of the ones he has purchased in the past, the man writes on his personal blog, ended up being 'mostly used for playing Galaga and Solitaire on long flights' even though they were naturally all phones run on open source operating systems. Things have changed now, he adds, now that he has caved and bought Google's Nexus One a couple of days ago.
