I like Magic Boxes. They let me get stuff done quickly, and then I can go figure out how they work later. To be fair, I used to hate them... Back before I started investigating how they worked. Now I'm only slightly uncomfortable with one I don't understand, and love ones that I do. Bandwidth, and and its brother Responsiveness, are a concern, however. I didn't look into this, but it appeared that the data binding was done in-browser, and only saving the data resulting in bandwidth usage.
