Just a note about a product I purchased initially for my wife to use with her 3rd generation Kindle and our iPad 2. The Wedge-E is a foam stand that supports any of these devices in a comfortable reading/watching position, portrait or landscape. Manufactured in the US by a small firm (One guy in his garage, I think.) The foam pillow comes in a variety of covers ranging from about $30-$50. Weighs almost nothing (6oz?) and is very well designed for the purpose. Can be tossed across the room from the bed when you're done with it.
The product has been very popular with iPad owners. Shipping is quick and customer service is excellent. No affiliation with the company, btw. Just a satisfied customer who has found it to be an excellent accessory.
