I love having access to my calendar at all times. I am horrible at daily planning and keeping tack of appointments and my smart phone allows me to micromanage my time with reminders. It also means I have a camera when I need one, which is something I always forget to bring on outings.
The downside is that I am compelled to respond to work issues 24 hrs. Granted, with remote email access, I was already doing this to some degree.REPORT ABUSE
