Scrolling in the browser is indeed a little smoother on the iPod Touch compared to my HTC Desire.

But on the Touch, when you scroll past a certain point nothing is rendered except a 'transparent area' style chequerboard. You then need to wait for the browser to re-render the page. By contrast, the Android phone always renders the page, so you can scroll to a particular point by looking at the page as it scrolls past.

Given this implementation I'm not surprised that scrolling is smoother on the Touch.

Perhaps this limitation is Touch-specific and doesn't apply to the latest iPhone.

Re: autorotation - I much prefer the hysteresis algorithm used by Android when screenflipping - I can use it when lying on my side, because the screen doesn't flip until I've 'fully' turned the phone on its side. The Touch flips after less rotation.
