You one of those unlucky folks who found out about the iPad's dislike of low-powered USB ports
on standard PCs after you'd already pulled the trigger? Well, you can stop crying yourself to sleep nights and finally do something about it: Gigabyte, MSI, and ASUS have all come out with software that hops up their respective, fairly interchangeable motherboards and delivers extra juice to an iPad-plugged USB port. Of course, they built these softwares for their own hardware, but there's a video after the break of a reckless user putting the ASUS software to work on a myriad of non-ASUS (mostly Sony) machines. Your mileage may vary, but if you wanna play it safe we'd say look into who built your motherboard before installing: we're not scientists, but we hear extra electricity "does stuff."
