[Staffslug] Linux Take-Up

I was thinking the other day (and this morning as I sat in the dentist office), what do you think is stopping people moving to Linux (or any other distro that is not M$ based)? There were a few ideas that jumped around in mind head, and I was wondering what everyone else thought? My ideas were: - Fear of the unknown - Lived with M$ for all of their computer lives (leading back to above) - Learning curve? (I know that with newer/certain distros, it's getting very graphical, but there isn't any c:\ !) - Hardware issues What do you think? Dave
