It's not much a of a secret that the optimal position to use a tablet is by holding it, but it's also well known that it's not always the most practical option, either. For example, if you're using it for a cookbook in the kitchen, it's far more ideal to keep it on the counter while you work. Similarly, no one really wants to hold a tablet in-hand while watching an entire movie.
For situations like this, there are a ton of various tablet stands on the market. One such stand is the iTilt Tablet Stand (okay, it's really called an iPad stand, but that's just silly) from Bracketron.
