I beg to differ.
As much as I love my Mac, I have always envy one small feature in Windows, the simple slideshow mode in folder view when you have images in it. The best we could do so far is to crank up the icon size to the max (128 pixel) and try very hard to be pleased with it.
Now, with coverflow, we could do the same and more. Now, to quickly browse through the docs as well, it's just way over the top...
Cover Flow is Pretty, but Fairly Useless
