It doesn't seem very useful to know your overall electricity usage - your energy bill tells you that.

Your monthly electricity bill does give you a monthly snapshot of your last month's usage, but the primary point of these devices appears to be moment to moment usage stats. The instantaneous data can act as a feedback mechanism that a monthly snapshot makes difficult. Integrating power monitoring at the device level would also be a nice step forward.
