DEVONthink looks intimidating..... @Gavin Gough how was the import process and what issues did you encounter pulling in the .enex files?
For anyone interested, I just concluded a trial of Nimbus Note. It has some good features but OMG are the desktop and iOS apps a mess.
I have an ongoing experiment with Obsidian now and generally like the wiki-esq linking scheme. However, the way it deals with attachments I don't think is going to work for me. Besides not having a iOS app which is critical to my life.
