The ability of being able to assign tasks to other users within my team as well as track progress made by each individual task has been very useful! I think there are some limitations with how you can view your calendar from mobile devices but this could be an upgrade rather then limiting it down if they can provide something like google calendars or outlook integration? Definitely worth looking into - we have had success using it so far. We're solving problems around tracking daily activities across multiple projects (2) while also creating actionable reports back up top line managers/CEO's etc.
