    Can't stand the new interface-made the decision to stick with 102 for the present. From the 20+ laundry list of issues above, I feel somewhat vindicated.

    Look, it's just an email program; does it have to contain a planner, have a chat feature, walk, talk, encourage you to exercise, get you coffee and play "The Stars and Stripes Forever" while doing all of these??
