What would it take for you to switch to Linux?

Interesting question via email in today's mailbag:

"What would it take for you to switch to Linux?"

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.

I also enjoy gaming, and as good as Wine is at allowing Windows apps to run on Linux, gaming is not a strong point. That's a roadblock to Linux adoption at the PC Doc HQ. While some readers seem to think that I'm more biased towards one OS or another, I'm not really ... I've got better things to do with my day that to become a cheerleader for one corporation or another. A free OS is compelling, but a free pair of shoes that don't fit are no good.

Then there's Outlook. I'm pretty indifferent to most of Microsoft's Office suite and could switch to OpenOffice quite easily, but my I'm hooked on Outlook and use this to keep track of my working day. One worry about switching to OpenOffice would be document compatibility, so in some way using Office is the least hassle route since those I work with all use Office.

Bottom line, to switch fully over to Linux can only happen for me if the majority of the world does ...

So, what would it take for you to switch operating systems? Would you swap, or are you happy with your current OS.
