Not sure if anyone noticed yet, but the 'Device Usage' widget, which has been on the device for the 6.5x firmwares, no longer exists in the official 7.10. It's a shame, as it gave an interesting window into the power states of the device, etc.
Does anyone know of an alternate way to access the same info? I might actually downgrade back to 6.72Beta, since it was fine for me feature-wise, and had the widget...
