That said, I agree with John Gruber when he writes on Daring Fireball:

Worst of all: scrolling. The iPhone uses a heuristic when you flick to scroll, such that if your finger is mostly moving up or down (or left or right) it locks you into that dimension when scrolling a view — such as a zoomed-in web page — that could be scrolled in any dimension. The effect is that when you’re zoomed in on a column of text in MobileSafari and flick “up” to scroll down, the view moves straight down, even if your flick gesture was a few degrees off. On Opera Mini, however, scrolling a zoomed-in view moves in exactly the direction of your flick gesture. The result is that scrolling an Opera Mini page feels like sliding a sheet of ice on an oil slick.

Within the last five years, the size of the average web page has more than tripled, and the number of external objects has nearly doubled. While broadband users have experienced somewhat faster response times, dial-up users have been left behind.

Overall Safari usage rebounded after slipping slightly in February to match the high water mark set in January at 5.82%.

Mac OSX has 7.48% marketshare according to this data. Of that, 60.69% is using Intel chips.
