How hard do you think it is to implement scrolling, the rubber band effect, and pinch-to-zoom on a display screen?
Answer: not hard at all.
So surely there were dozens of devices with these features (I assume you mean inertial scrolling) prior to the patents being granted?
This stuff is not trivial: Only a handful of multitouch devices even existed prior to the iPhone, and exploiting that technology, along with improvements in mobile hardware generally, was hard, or smartphones prior to 2007 wouldn't have sucked so very badly.
Read the file wrapper and the notice of allowability. Here is Apple's great triumph in claiming an invention as compared to prior art:
"The following is an examiner's statement of reasons for allowance: In regards to the independent claims 1, 19 and 20, the prior art found does not teach in response to
an edge of the electronic document being reached while translating the electronic document in the first direction while the object is still detected on or near the touch
screen display: displaying an area beyond the edge of the document, and displaying a third portion of the electronic document, wherein the third portion is smaller than the first portion; and in response to detecting that the object is no longer detected on or near the touch screen display, translating the electronic document in a second direction until the area beyond the edge of the electronic document is no longer displayed to display a fourth portion of the electronic document, wherein the fourth portion is different from the first portion; in combination with all of the other claim limitations."
Do you consider that extremely narrow tweak to a user interface a novel and useful invention worthy of patent protection?
If it's so narrow, why is it a problem for Samsung? You can't have it both ways. Either it's just an obvious, trivial idea, or it's a specific implementation that's a useful but not necessary extension of the art.
