Augmented Reality, Head-To-Head

In the blog Augmented Planet a head-to-head comparison of a number of augmented reality browsers for the purpose of finding a restaurant and finding sites in London. Followed by a part 2, working with immediate surroundings. Includes some useful screen shots. My overall impression, not overly useful, the links to information on the sites on online resources like the Wikipedia are useful. Short range GPS accuracy in cities is often a problem. I can see where this is going, yet it still would have many problems for the average user.
