I don't like that Apple has stripped the color out of all the sidebar icons. I don't like it in iTunes, and I don't like it in the Finder. Just another thing I'll have to patch all the time, I guess.

The Cover Flow graphic on page 4 is a duplicate of the column view graphic. Oops.

Not sure about all the integrated coverflow stuff. It looks ugly with the icons crowded on one side. It looks like the Finder has been in an accident. I'll have to try it though.

I wish Apple would implemented a Windows-style 'tile' view that has the preview and some information about the file in line. It's annoying that the only way to display information about a file is to use Get Info or Quicklook or select the file for a preview. I'd much rather have more information available in-line. If you're using Finder at all, chances are things like file size, the length of a video clip, the dimensions of an image, etc, are relevant to what you're trying to do.

Looks lik the new context aware search is a result of the Siri acquicision.

I really don't like the cover flow. The icons, unlike those in iOS and album arts, have their own "3D" in it. Like the dictionary it portraits a dictionary which is 3D by itself. They are just trying to use the skewing in album art coverflow and bring it here? Doesn't look good to me.
