Skydeck
Grow comfortable with technology and it'll make life easier, but get cavalier and it'll screw you -- just ask poor Pete Townsend, who was merely researching his autobiography. Curbing blasé cellphone use, Skydeck.
SD also offers a daily/weekly update email that includes remaining minutes, plus a list of your phone's "winners" (those you call most/talk to longest) and "losers": people you never call back, like your doctor, who only wanted to tell you your cellphone's given you a tumor.
