The Untitled theme is both supremely attractive and quite simple to work with. I was waiting weeks for this theme to be ported over to WordPress.org, and been loving it ever since it was.
There's a bit of a learning curve trying to do featured images and the like, but nothing us cool WP dudes (or ladies) can't figure out.
It's great and the publisher is great and anyone who downloads it is great.
I love the Featured Image support for posts, though I wish the Featured Image would allow me to upload an image then allow me to crop it to the appropriate aspect ratio all on the fly rather than resizing to the best fit of 1440x400. Still, it's the cost of doing business with such a nice theme, so I'm happy to fire up Photoshop to do the cropping.
A group of my baseball buddies used this theme on wordpress.com (http://phillycalledup.com), but we were thrilled when this theme landed at wordpress.org so we could evaluate its use at our campus (we all work at a college). There are some minor differences, which I'll be logging as support requests, but so far it looks to behave mostly the same as the wordpress.com version.
A very nice theme for those with an emphasis on blogging and graphic intensive headers (though images are not required for posts).
