Pro It remains simple to use with a gentle learning curve

Cons
Con No drag'n'drop file upload
Con Cannot export to a format that can be imported again
This makes it obscure and cumbersome to back up your notes as files that could be managed by your backup system. You can export to PDF, but not in bulk; and this isn't the native format that you can easily recover with.
Apple compounds the problem by using some undocumented format for notes. You can, however, back them all up by backing up the files found in ~/Library/Containers/com.apple.Notes/Data/Library/Notes
