If you are in anyway interested in a windows desktop replacement ....
Get the open circulation edition which is free and fully functional except that xover office is a 30 day trial.
Out of the box it detected my network and configured the samba shares for me , comes with all the essentials , detected all of my hardware without a hitch.
Mozilla & Thunderbird are included as are open office , & all the basics.
Media playback is fantastic (my biggest gripe with out of the box Fedora) plays avi , mpg , &&windows wmv files ! , cd burning etc a breeze.
You really could give this system to your gran and expect her to be able to use it + as its debian based , with apt-get you can easily convert it to a server or development machine...
worth a look , anyone else tried it ?
