No real opinion here on "mixed fonts" ... but as for color of the font, I don't see a way around it unless you're talking about white. (that's not even a "color" is it?) But with the black & white photo, black font will be a bit hard to see won't it? Seems there will have to be color fonts ... I think white would be a bit washed out and black would not offer enough contrast IMHO.

One thing I just noticed today, and have no clue if it's related to the recent changes or not, if I click on the emoticon (smiley face) thingy in the tool bar, it comes up normally ... but if I click on "more" options, the window disappears completely.

Oh yeah, I do like the "decluttered" dock pics as they're much cleaner looking. #3 is my personal favorite ... for whatever that's worth.
