This may be the best Windows imposter (security blanket) ever for someone wanting to do a linux install for a reluctant end user... Q4OS... google it. It is a debian/kde derivative but the best out of the box wolf in sheeps clothing I have yet to see. Can be set up to look like xp or 7.
Very low overhead (300 or so meg download) Easy facilities on the download page to load chrome, wine, etc etc as pre configured installs, and it works with the debian repositories, so anything can be added using apt or synaptic, which I loaded right away. Should run well on legacy equipment.. I will probably try a memory stick install too..
Blazingly fast on the virtual machine I installed it on. I may load one machine at the emergency clinic jusst to see if anyone actually notices.
Not a lot of info about who's project this is, but they have given it a lot of time and thought.
