I like that it has all of my contact info, so if they need to reach me in an emergency situation there is no delay or confusion about how many numbers/emails i have (and therefore who should be contacted).
There are some glitches with scheduling appointments-it can take up to 3 days for calendar reminders from one day before appointment date until reminder goes out! This makes planning ahead difficult because people don't realize when their next scheduled doctor's appt will happen.- also hard to schedule any type of training since everyone schedules around other things. Scheduling meetings at work as well - this allows us time flexibility without having to reschedule our own plans every single week.
