I am a Network Administrator for a medium size city Library. We currently use Dell's with XP and all the 'bell's and whistle'...including the essential Deep Freeze. I am looking at Terminal Services with either Linux or MS. Wyse Technologies (formally Netier) does offer thin clients and if I remember right they can offer terminal service through these. From my experience Linux IS morse secure but you will have a greater learning curve if not phobia from patrons..and staff alike! Good Luck! Richard-
