"Mac OS X Lion introduces overlay scrollbars similar to those in iOS. These scrollbars appear as an overlay on top of the window's content while the user is scrolling and remain visible briefly to allow scrollbar dragging."
Do you read that to mean that all standard Aqua scrollbars will be rendered as overlay scrollbars in Lion? My initial impression was just that the overlay version will be made available to developers. That said, some OSX apps already use them, so I'm not sure why it has been highlighted as a new feature of Lion... any thoughts?
