Even I...
I am a developer, I also administer a large EMEA SharePoint installation all of which i do on the windows platform...but when at home I only totally trust my Linux distro's.
Sure you can argue that the more popular Linux becomes they will "stick their neck out", and there will probably be script kiddies waiting to catch out unsuspecting users. But the inherent stability of Linux far out performs the rather wobbly windows OS.
Too many times in my 10+ years in IT have I had to re-do windows installs on both servers and desktops, or try and recover data from an "unexpected shutdown". Good for you Dell...some poor analogies but a good move all round!
