...Or you could just click the "Reduce" button (I forget what it's called at the moment - it's the "clear" button that occasionally appears in the upper-right hand corner of windows, and usually shows/hides the toolbar. This takes you back to a much more Jaguar-like view, though without the top toolbar.
I wasn't thrilled about it to start with (mostly, I think, it's the brushed metalification of the Macs/OS X that's bothering me), but after three weeks, I'm hooked. Finder's still not perfect, but I DO like the new windows better.
I say give it a shot.
