This poll is to show the version of Adobe Reader that the users of Adobe Reader use. Also, Does the new version 10 have any major bugs or performance issues since it is a new release? Does version 10 offer any major improvements over previous versions (ie: version 8/9)? Do you think it's worth to upgrade to version 10 (security reasons??) Edit: This article suggests Adobe Reader 10's sandbox feature may actually decrease security by introducing more exploits. What do you think?
