My shool started using Mandriva when I was a 4th grader (I'm in 10th grade
now) and replaced it with Ubuntu Jaunty the year after that and with Edubuntu
Precise last year.
Sadly, Windows was never removed, and now that IT has been removed from the
new Indonesian curriculum (a move as popular as F1's DRS) only the 12th
graders (the only ones still on the old curriculum, at least in my school)
use Ubuntu (well, Edubuntu to be exact). When my class went into the computer
lab for another subject (albeit one taught by a teacher that would've been an
IT teacher were it not for the change in the curriculum) he asked us to boot
into Windows instead, despite Ubuntu showing up when we got to GRUB.
All I can do is shake my head, and say,"It's a shame."
