I feel this requires more discussion since some/many seem to be affected by it.
I think you are right, everything is going mobile.
Some niches are clearly not totally going that way yet however it is difficult to get absolutely accurate statistics since even Google are not collating them correctly and differ greatly to my own logs.
Why do I write that? I have tested my sites with both 7" and 10" tablets and a high-end mobile, Nokia E7, and the fact is that Google cannot identify a 2.1 Android as a tablet and for my E7 it doesn't even display any ads.
Nevertheless Google will be influenced by their own metrics which for 2012 so far show that of all pages views 6.8% are tablets and high-end mobile whereas my logs show less than 1%.
Amazingly my CTR v Desktop average is 150% for tablets and 173.9% for high-end mobile with page views and earnings staying fairly consistent all year however they're nothing anyone could retire on, yet. Tablet EPC v Desktop is 88.5% and Mobile 65.4%
THE single most significant factor, for me, in all of this is that hardly anyone uses my responsive mobile sites, insofar as AdSense is concerned these sites have earned ZERO in 2012!
All my regular sites display perfectly on both 7" and 10" tablets and are usable with pinching etc on mobiles therefore I'm not changing anything whatsoever unless I see a significant user change.
How do these metrics compare to others? Wildy I bet however it would be interesting to see.
