Why is acroread so popular, and why are the free alternatives not good enough?
According to <URL:http://popcon.skolelinux.org/unknown/by_vote>,
acroread is the most popular package in Debian Edu that is missing in
Debian. 46% of the population got it installed, and 30% used it last
week. Anyone know why it is so popular? What features does it
provide that the free PDF viewers do not? Is there anything we could
do to fulfil this need with free software?
