It amazes me that Apple has not accepted overwhelming feedback that there are cases when scrollbar arrows are important. My use case is running Outlook on Mac.
When I have the Reading Pane displayed, I have two (or three) scrollable regions on the screen. The arrow keys on the keyboard are associated to whichever window/region/pane is currently selected. Selection of an email message lets me scroll up and down with arrow keys among different messages. I want to click up/down arrow gadgets in the Reading Pane, so I can scroll the actual message. But the selection is in the other pane and there are no scrollbar arrow gadgets. So I click in the message itself at the bottom. Now I can scroll by small amounts with the arrow keys.
Now I want to shift to a new message. I have to click a message in the top pane in order to switch messages. I don't want to look at every message in detail. I want to find another message important to what I'm doing right now. I want to just move down the list looking at the summary info for each message but only seeing the detail for a message I select. Instead I have to select each message in turn. Luckily I've turned off the option to mark messages as read automatically. Else, I'd be even more unhappy.
I imagine there are two warring armies in the Apple Usability committees. The laptop/desktop folks throw things at the tablet/iphone folks, and vice versa. In the end, the tablet/iphone guys get their way because their business is growing faster. Good usability techniques (or at least ones that hundreds of people post wishes for, multiplied for dozens or more of different pages and sites) get printed and rolled up into substitute nerf arrows and launched across at the tablet/iphone guys. Eventually the committee head says "hey, no arrows" and the views of hundreds or thousands of people get dropped in the trash can, never to be debated or considered again.
At the end of the meeting, there are hundreds of Apple developers huddled outside, many with their mac laptops at their side, and also with there tablets/iphones in their hands. The meeting breaks. Half the attendees walk out with their heads hung low, shaking their heads slowly side to side. The huddled masses outside sense immediately what has happened... again. Their heads are now also hung low, shaking slowly side to side. They walk back to their desks and set down their tablets and iphones. They open their laptops/desktops, and start scrolling awkwardly through their email messages, and get back to work. Less productively.
In the end, who wins? Noone, certainly not the user of a mac laptop who has been saying how much he loves using Macs, better than Windows, better than any of the Linux variants (can you say "gnome"), etc.
Give us back our option to turn "scrollbar arrows" on. And heck, give the subchoice of selecting whether they're together at the bottom of the scrollbar or split with up at top and down at bottom. Please! Please! P-LEASE!!
