Originally I worked with SUNsparc work stations using Aurora.  About 2003 I added Fedora Red Hat to a dual booted Windows machine.  My two SUN's got reduced to one virtue of hardware issues.  Then I turned it off.  The Red Hat part of my big disk became sick in 2005.
 
I've been Windows XP 2004 Professional ever since.  Recently I rebuilt a Fedora machine and am appalled at how much I have forgotten..  Sigh......
