Mark Finkle, Vivien Nicolas, Felipe Gomes, and I have put together a blog post about Smart Tap, the technique we're using in mobile Firefox 1.1 to make tapping on small links, fields, and buttons much easier.
From a user's perspective, tapping on small targets should just work out the way you intended more of the time. Behind the scenes, there's a lot more going on to make it feel this way: a larger and up-shifted invisible tap region around the point of touch-contact; favoring higher z-ordered elements; and favoring visited links over unvisited ones, to name a few. Read the full post for the whole story, and let us know how you find it working when you try out 1.1.
