Purely by chance, I was trying out a galaxy tab at a store today. I loaded up the Financial Times web site, which took an age because the store wifi was crap and tried scrolling the web page and it stuttered quite a bit at first then smoothed up, zooming as juddery as well. Did the same thing on an ipad - slow loading about the same, but the instant the page was rendered it scrolled and zoomed perfectly.

Also the widget for editing the web page URL on the Tab was a horrible usability car crash. What's up with that? Disclosure - iPhone user, but Android curious.
