MicroPCTalk asks the question: how often do you use a touch screen on a tablet PC?
Like the author of that post, I find myself using touch to navigate, but falling back to keyboard for text entry. Navigating with your finger is just such a natural experience. The issue is that a finger is not an ideal pointing device, and buttons and text on screen is often rather small, so pointing your finger exactly where you want the computer to recognize the touch is often difficult.
This is where some of the work currently going on with multi touch may quickly benefit regular touch applications. What seems to be needed is some logic behind the scenes, which would analyze the finger press, and consider what the user wanted to touch, as opposed to exactly where they touched. For instance, when browsing the web, clicking on a text link is more likely the desired outcome compared to clicking on a plain text word. The PC should realize that and act accordingly, even if the finger touched slightly off of the hyperlink.
