I was finally able to switch from a Dish 622 to a 722k this summer and I want to add Sling Box capability. I am not in a real big hurry, but I was looking online and I see that the Sling Adapter is "coming soon". Does anybody have any helpful tips on whether I should wait for that or simply buy something that is available currently? I can't really seem to tell what the likely differences are between what the adapter will offer vs. existing boxes. Is the attraction of the Sling Adapter going to be simplicity in installation, small size, or is there something else I am missing?
