Still trying to find out as my friend is going to buy it tomorrow...
I read the ipad can charge slowly from a computer. But asus and others have released a tool so you can charge these devices faster.
engadget article on charging

Does this work with the nook? Has anyone charged a nook over a computer and if so how long does it take?
I'm reading conflicting things on this.
