Re: Does your daughter use Linux?
I have no daughter, only a son*, although my 'daughters-by-proxy' (my students) use an Ubuntu box in my classroom. I am forced by university policy to have MS XP on the 16 lab computers, but I adopted two orphaned MS machines and did a complete reinstall of Ubuntu 8.10 (now on 9.04). Since it's really only used for Internet stuff, like educational sites and YouTube music videos, they don't get explored much in other regards by either gender (same with the MS machines). However, there haven't been any problems or difficulties with getting places and making stuff work.
The Ubuntu machines are MUCH less work for me than the MS machines running their fancy monitoring software, which constantly drops machines and falls off the network. Ubuntu just works... even despite being on the 'slower' machine.
I'm in a bilingual classroom, so I have one of the Ubuntu boxes set up in Spanish.
*Son uses Ubuntu, happily, and my husband just made the leap last month from struggling with Vista for 6 months to asking me to put just Ubuntu on his machine so that I would be his tech support.
