The browsing experience on the iPad is fantastic. That said, I too have noticed some small hiccups, though the author's problem with the address bar at the top hasn't bothered me. The two things I don't like are:

1) I don't really know what a link points to without clicking it. I would love to just, say, draw a circle with my finger around the link and have it display the URL. Maybe there's some way to hover over links on the iPad that I don't know about?

2) No immediate close button. I have to hit the two overlapping rectangles to bring up the "tabs" and then close from there.
