and to taxed2death - redhat and SUSE. albeit not recently.
I run SuSE 10.2 at home on all my systems, even my T30 ThinkPad with WPC54G wireless card. Works like a champ. And my 80 year old dad uses it too. It wasn't that difficult to show him around the basics of the system, and how to launch Firefox, E-Mail and Solitaire.
If you haven't checked out SuSE or Redhat recently, you might want to give them another look.
I've started deploying SLED peripherally on my network: using it to lock down 6 public access machines, and am prepping a migration of my company's intranet from a Win2K server to a SLED server.
