And reverting to reductio ad absurdum in an attempt to prove a logically weak position is better? Your closing works both ways. Your logic as far as I can see has basically been, to paraphrase; 'it annoys me'.
All recent (less than 3 years) Apple devices are sold either as touch devices or with touch enabled peripherals. Gestural interaction is the default paradigm of interaction on iOS/OS X (this is also true of Android devices). These users are largely used to this behavior, which can be changed if there is a desire to do so. This behavior does not affect users of other systems that don't support gestural interaction. There is no need therefore to cater specifically for Apple (or other) users as they, through daily interaction with their device, will intuit what to do. It puzzles me why the scrollbar still exists as an interaction device elsewhere. I really had to think about where and how they appear because I am so used to them simply not being there.
Perhaps you are looking at them in the wrong way. Where once the scrollbar was used for scrolling, it is now used to indicate the position the reader has reached on a page.
No, I read it easily; I simply used the trackpad to scroll. I disregarded it to because the premise is flawed, as has been pointed out to you. You don't have to agree with everyone else, but in real world use, with real world people, this is considerably less of an issue that you are making it to be.
Watch a child use touch-based interface. It's enlightening. They intuit the required interaction with consummate ease. Having observed how individuals still use scroll bars by tapping on the arrows and not realising that it's quicker to grab the bar, to me illustrates that using and relying on scroll bars is as much a learned behaviour, and a less intuitive one at that.
You missed my point. Just invoking the word "preference" is a weak argument. You need something more like an actual argument. With evidence and logic.
