One reason I’m not hurrying to upgrade to Lion is its new user interface, particularly the overlay scroll bars that disappear when not in use.
I am a fan of the user interface design guidelines that Apple pioneered with the first Macs in the mid-to-late 1980s, where developers tried to make it as clear as possible what each button and function did. As a computer user who relies on a mouse for navigation, I prefer the warm-and-fuzzy feeling that visible scroll bars provide, as in this example in OS X 10.6.
What do you think? If you’ve upgraded to 10.7, do you like or hate the new overlay scroll bars?
