I love this portfolio for iPad. It’s a standard size for an 8.5×11 pad of paper, and keeps the iPad hidden and protected in the back. Use it in a meeting without having to reveal your iPad. The front pocket is a huge advantage as it holds my cords, headphones, mifi card, chargers with room to spare. This is beige, but brown is their standard color.
A similar one, but not exactly the same (difference is that it doesn’t have the larger front, external pocket)…
