Depending on which hemisphere you live in, the temperatures have started to severely drop, unless the Global Warming Effect has kicked in again, and you may soon be in need of some USB help; that is the reason for the existence of the HiPad (or HotPad)!

Just make sure you unplug it in time, if not, we will gladly publish your laptop crash baby pics!
