I have been using this system for nearly 10 years now, which is one of its greatest advantages since you don't constantly need new software or other platforms when switching from job/task management systems like Asana etc., but can just continue where there was left off even if completely different applications are in use (eMail).
Sometimes it has trouble syncing after long periods without any activity by me although i usually only check my emails once per week so that might be due as wellβ¦
