It works well enough on Android and Palm Pre, although without the fancy OpenGL-accelerated CSS transforms (it gracefully degrades to more traditional CSS animations if WebKit transitions are not available). The underlying HTML is just a bunch of unordered lists and divs, and all the advanced behavior is via CSS and Javascript - if you want to make sure it'll work on less-capable browsers it's doable, but you'll need to keep an eye on how you're loading things. You may wind up needing to to browser sniffing on the server and serving up different HTML if you see various browsers; we didn't get that far in the project we worked on.
