Adobe Device Central

Perhaps the most comprehensive of all device emulators is Adobe's Device Central, shown in Figure 18-1. Device Central is a utility that comes with most of Adobe's popular design and media editing software, such as Flash, Dreamweaver, Photoshop, and Illustrator. You can't buy it as a standalone application (though it would be nice if you could).

Device Central has the largest database of mobile devices, as far as emulators go, that I'm aware of, and the database is updated daily, not only by Adobe but also by Adobe users. Device Central also provides the most information and emulation options I've seen. Not only can you see how your pages look on specific devices but you can also get detailed descriptions of what technologies, such as HTML and CSS versions, each device supports, and oh so much more information.
