For me it's just not having time to learn more. Once you know how to do something on Linux - make a connection, use an app, whatever - it's as easy as on Windows or easier. But getting there can take hours per task. For example, I'm trying to set aside a few hours,, or however long it may take, sometime to figure out how to make my Win2k and Red hat boxes share files (yes I'm a complete newbie). BUt this has been pushed back for several weekends now, and likewise with a million other things. *Meanwhile* I have to have a machine I can fully use for work and writing, etc. and that means continuing on Windows - with an increasing sense of being unwillingly stuck in the proprietary world.
