How easy is it to switch over to Linux? The main reason why I haven't done so yet is because I think there's still a lot of useful programs that are Windows-only (like truecrypt).
Just set up a dual-boot with windows and your distro. Then download Wine, and try to run them. If they don't work properly, boot windows and use it for those things.
If you don't feel comfortable with a dual-boot then just use a virtual machine.
Enjoy your freedom.
What do you say? Truecrypt is multiplatform, and you can download the package with no problems.
