One of the stumbling blocks in migrating to the Linux desktop is the mistaken view that you can't take it with you. Your data must remain captive to the Microsoft operating system. Not true at all.
A related misconception that stalls many Windows users from adopting the Linux OS is the belief that when you buy a new computer or install Linux to an existing computer, you must give up one operating system for the other. Again, not true at all.
Like an evangelist, I frequently tell people about a free Windows-like alternative that is faster and more secure than Microsoft's OS. The most common response I get is, "Linux, what's that?"
Rest here
