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.

Jason Cline, a senior software engineer at Web application developer Sitepen, says that the broad differences between the iPhone and Android SDKs are related to trade-offs between greater freedom and greater accessibility.

For this blog’s audience, the key difference may be that you’re guaranteed a level playing field when you develop for iPhone, but Android will run on disparate platforms resulting in heterogenous device capabilities and quirks.
