What’s the best way to convert a Windows user to a Mac? Give them something they are familiar with. With Mac OS 10.5, aka Leopard, Apple integrates the iTunes interface, that both Mac and Windows users are use to, into the Finder.

First off there is Coverflow, the handy little application that Apple bought from a Mac developer. It really showcases album artwork in iTunes and now does the same thing for documents and images in the Finder.

Second is the sidebar. With the same look and feel and functionality as iTunes, the Finder now replicates iTunes’ sidebar.
