I like to change the preferences based on what im looking at. You can take a site like ppcgeeks and set the reflow to medium or large and leave the up/down set to pan. Click the button that has the little red arrows next to it and it will reflow the page to fit your screen. Then you can scroll up and down with the directional button. If im looking at cnet or a pdf, set the up/down to zoom and then just move the page with finger drags and zoom in with the button. Its very responsive.
