What would it take for you to switch to Linux? | Hardware 2.0 | ZDNet.com: "I do use Linux, but I have to admit that Windows is my default OS. I do 90% of my work on Windows, and a good 75% of that work revolves around Windows. If I’m doing something web related (browsing, email, Twittering, IMing …) then I’m pretty platform agnostic and can switch between Windows, Linux, Mac, iPhone OS, Symbian or whatever pretty easily. Keeping all my passwords and such synced between different platforms is a pain, but it’s manageable."
