As I indicated in a previous post I was thinking of switching away from iOrganize - now I've done so, and very happily. For unencrypted notes the not very imaginatively named "Notes" seems excellent <http://www.versiontracker.com/dyn/moreinfo/macosx/9605>. For encryption try Base! <http://www.versiontracker.com/dyn/moreinfo/macos/18579>. Both programs are simple, elegant, efficient - and both are free.
