The real need is to be able to go from work to personal and back. This includes not only the messaging, but the look itself. The pearl is a great step, but the software has a long way to go. Have a switch on the outside to go from work to personal. This would allow the person to really feel like they were “switching work off”. The settings could be such that email is no longer pushed, but is queued for later. Maybe the ringer changes and even the home page of the start screen. For example the camera link could become front and center verses the task list. Email needs to be clearly separated. I don’t want to have the temptation of getting caught up on a work item when I’m trying to check in on the weekend plans with some friends. Instant messaging could also help send the message. I’m not working, ping me later. Hit the switch and the presence info changes back to working. Integration with work phone “follow me” systems could also be tied in. I’m always annoyed by having to remember to call into the system to let it know I’m at my desk or working. Calendar integration should go beyond the corporate server. Using Google calendar to share my travel schedule with friends is fun, but requires me to keep my calendar updated in two places.
