2. Wheel scrolling is a feature. Yes, horizontal scrolling sucks but vertical scrolling is working as intended and something I really prefer. Yes, I'd like a good horizontal scroll but the use cases where you need it are extremely rare and often stem from bad UI design in the application - not saying that as an excuse but just that it isn't a big issue. Microsoft have tried scrolling wheels that can go horizontal as well but they were mindbogglingly bad (my opinion).
3. I don't see how that is an issue (in practice) for anything that isn't done for Win95. And if it was made for Win95 I'd rather be able to run it than not. Backwards compatibility at its best. Doesn't bother you when you don't need it but can still handle corner cases as well as can be expected.
I used Mac for a week and went back to Windows. The jerky scrolling in Windows was driving me crazy. The fact was that before Mac I never realized that (maybe I'm numb to perfection) but it was only using Mac that it occurred how much crap scrolling is in Windows.
There are many many quirks like this in Windows that you only notice once you use a different window manager.
OS X is quite unique in this and probably stems from the use of common menus for different windows, which also makes it uniquely inadequate for handling multiple monitors. I just can't take a WM that doesn't handle multiple monitors well seriously.
I'm sure if people were presented with both options; regain focus and lose selection vs keepi g selection, they'd choose the keep selection. It's as if someone used the computer and said "you know what would be useful?..."
1. The trackpad hardware is great. It's so good that when we were making the Bamboo Touch at Wacom, the Macbook Pro trackpad was the standard we measured ourselves against.
2. True pixel-level scrolling from HID devices. Windows has the concept of "wheel scrolling", but it's only vertical, and lots of apps won't scroll in less than a wheel increment (which is oddly 120 units), so you're stuck with jerky 3-lines-at-a-time scrolling. Oh, and it's vertical-only; there's no system standard for horizontal scrolling.
3. It's never had a software-based rendering and compositing engine for the windowing system. The Windows team is fully committed to backward-compatibility, which means allowing all sorts of wonky GDI-based pixel pushers to work they same way they did in Win95. OSX has been OpenGL-based from the start.
