For fedora, now actually the tiny evince has been good enough to replace the bulky acrobat reader.
Check the size: evince < 1 M while acrobat reader 7.0 > 100 M. And for chinese pdf file, you don’t need to install additional chinese font for evince as we did for acrobat reader.
After you use “rpm -e ***” to remove the bulky one, file association is still there. The first choice when you click on the pdf file is still to look for acroread. The way is simple: sudo ln -s /usr/bin/evince /usr/bin/acroread . However, this would again mislead firefox to look for acrobat reader to open the online pdf file, probably a bug.
For firefox, there is no above mentioned problem thanks to mozplugger. Now everything is fine and the system just loses the weight.
For windows user, foxit is pretty much of acrobat reader but much much compact.
