iTunes is an abomination anyway, but the buttons at least look like buttons. Not so with sparrow, they are just darkish inset shapes. (Much like the Mac App Store, which, even though it's made by Apple, should not be used as an example for good UI, ever. IMO.) Nothing against the left category bar, but why not use a standard widget? Think Mail or iTunes. Also, selecting an item from a vertical list on the left and changing content horizontally on the right feels strange to me.
