I wanted to pose this question on an intellectual forum not solely devoted to technology to see the various responses from the tech geek and non-tech geek alike.

Have you ever considered switching to Linux? Have you switched? If not, what is holding you back?

I also would like to know what are perceived as the true advantages (adaptation, low/zero cost, free software, etc) verses the disadvantages (compatibility, lack of familiarity, lack of warranty, etc)of Linux/OS of choice.
