Seriously: what is Apple thinking by turning the menubar nearly invisible, but keeping the 'just slightly' translucent aspect and white color of previous menus? I think this looks absolutely dreadful, as it doesn't even look like the menubar and the menus have anything to do with each other anymore, and I'll be damned if Apple takes the actual menus this translucent as well. In fact, if they went that over the edge, I could comfortably say that I wouldn't buy a copy of Leopard until someone developed a modification that switches the menubar and menu back from the brink of "hey look, Vista went transparent!"-ness (of course, a simple Apple-provided checkbox in System Preferences would do just fine as well).
Given Peter Maurer's mod and disinterest in this change surfacing from others, I can only hope that more voice their opinion - whether they do or don't like it - and that Apple listens if it the consensus on this menubar change turns out to be a thumbs down. After all, Leopard still is a developer-only beta, and October is still a long way away.
