It took me a minute to understand why blockchain.info's icon was on the "choose your wallet" page twice, and I also remember wondering whether it'd be clear to users that some downloads are not desktop applications. I only understood once I saw the text above the icons.
Since many people don't read the all the text on a page (especially a page leading to downloads, and I came here looking for the bitcoin-qt download), I think this visual hint, separating the different client types with a gray line, makes it clearer that there is not only the choice of which wallet to use but also different types of wallets.

I'm not that experienced with Github and how appropriate it is to do pull requests for such a small change, but I think it will help users so I'd like to contribute the change anyway. Thanks!
