Argh! Why is it that macs, with their supposed superior, intuitive, mouse-driven interfaces, so frequently revert to keyboard shortcuts to get things done?
Non-mac users may not realize that closing an app window on a mac generally does NOT exit the program. On other platforms it consistently does, but on macs it almost always does not. Sadly, it sometimes does exit an app on a mac which makes it all the more infuriating. It is something you will adjust to. This problem may be as simple as not realizing that macs like to keep programs running (because OS X is slow at starting apps up).
Cor, I agree that Apple hates to admit it was wrong on the mouse button thing. That's why they make the "mighty mouse" look and work like it still has only one button (and in so doing make it the worst mouse on the market). It's also why they refuse to put the second button on the notebooks. There is a workaround, though. In system preferences under keyboard and mouse, you can set the trackpad to enable right-clicking using simultaneous trackpad touching. It takes a bit of adjustment but is ultimately a satisfactory alternative. I find the Apple trackpads to be far better than I've used on other notebooks. I love them.
Speaking of right clicks and program exiting, one of Apple's most kludgy and inconsistent hacks is the click-and-hold feature of the dock. Doing this brings up a context menu where you can directly exit a program (among other things). Thing is, click-and-hold only works there. Bravo, Apple, your usability "experts" must be glowing with pride on that one.
On the subject of keyboard and mouse options for switchers, under "keyboard shortcuts" at the bottom there is an option to fix the mac's default, broken behavior regarding the tab key in dialogs. Setting the option to "All controls" will reduce annoyances IMO. I can't stand that tabbing skips over list boxes by default.
P.S. I don't mean to imply that George simply wasn't doing it right. Maybe that's the case, but I have gotten iTunes stuck and had to power-cycle the machine. JVMs on the mac are notorious for that as well and you can't force-quit them.
