The public BETA testing of version 3 has started. If the final version comes within a year from now, it will be a free upgrade, if you purchase today.
I raised an issue with the developer last week, related to the difficulty of assessing the most recent version of a notes file when AMN's in use on multiple, not-always-networked PCs, since it resaves on exit even if no changes have been made... and he emailed me back to say that this issue's being specifically addressed in the new beta. I haven't tried it yet -- the weekend's been busy -- but I plan to take a look in the next few days.
I've been using other things than AMN for a while but after spending a while experimenting with the free version of RightNote last week I suddenly found myself thinking that actually, if I give into using a tree-based view of things, AMN's actually pretty decent and RightNote doesn't seem to add much to the mix that I don't already have.
I really need to stop messing around and settle to SOMETHING. But I can't decide whether the structured approach of AMN or the unstructured approach of NoteFrog or CintaNotes suits me better...
