the confusion arises, because tablets are commonly labeled mobile devices. in fact, they are, but keep in mind, that in terms of screen capacities, even in portrait mode tablets don't differ that much from devices like small notebooks. in order to correctly cater to tablets, it is more important to keep an eye on things like touch gestures and device compatibility features and integrate them properly.
In the past few months, I've switched four Wordpress sites to two different responsive themes that I bought from designers. In one theme, the drop down menus change on tablets. In the other, they don't, and they work just fine by touch. In both cases, the ads don't change at all on tablets.
I totally agree with you that it's really just the phones that need a significantly different layout. The vast majority of my mobile users are on tablets.
And to answer the thread's original question, I'm seeing no SEO benefits or changes at all on any of these sites. I'm seeing a small loss in income because not all of my ads are shown on phones now. But this isn't a big deal because, again, most people don't use my sites on phones.
