I am in need of a carrying bag for my ipad 2. I already have a case for it (a Switcheasy canvas, which I love!) However, I want a bag to carry not only my ipad/case, but various other items, such as a charging cable, a portable HD, an HDMI cable, etc. I don't like carrying these few items in my 17" notebook bag. Does anyone have any suggestions for one of these? Thanks!
