I am using one like this which I bought a couple of years ago and it works out great! for a table or desk use. I might note that it tilts also, might not be the best if you plan on doing heavy typing, but it's great for surfing,watching movies or enjoying your pictures and at $8.00 can't go wrong for trying it out.
I emailed Bracketron Bracketron : Mounting Solutions for Mobile Electronics. I have bought gps/phone holders from them before and they said that they are considering the iPad category so soon enough we will have all kinds of holders and brackets for car and home.
Just bought a nice little stand at bed bath and beyond for 3.99. It's located in the kitchen section where the napkin holders are. Unfortunately I can't even find it online but it's small and has a gold color and probably has enough weight to hold a book, but very light. I can place this thing in the bathroom or on the counter. It even stays still while on top of my bed.
