We lost power at the beginning of Hurricane Irene (NJ). (I had charged up the Touchpad expecting we would lose power.)
I ran generator power to the basement to run the sump pumps. I also powered the FiOS terminal and moved the wireless modem/router to the basement to power it. After all this was set up the Touchpad had internet access.
It was so nice to be able to use the Touchpad anywhere in the house without having to run power to it. If I had used my laptop, netbook or palm pre they would have run down in about an hour.
After 18 hours without power and a lot of surfing to get the latest information about the impact of the storm and the status of family members, the touchpad still had > 50% battery. In fact, it's been 36 hours since the last charge and it still has plenty of battery left.
This Touchpad is AMAZING!!
