We saw the other day YouTube featuring Windows Phone on its front page and tonight it's Last.fm's turn. Hopping over to the site and heading to the Radio area, you'll have your browser overtaken by the Samsung Omnia W and Windows Phone, including that $25 app card good for the Marketplace.
Although people have rightly complained about lack of exposure for Windows Phone in the past, it seems clear that everyone is stepping up a bit on the second go-around. Hopefully it will pay off in some sales.
Thanks, Sayon, for the tip!
