With the Kindle Touch if I leave wireless off; which is perfect okay for an e-reader; I do not get ads after awhile. Granted with the new Fires your not going to want to go that route.

I never did figure out why Amazon loaded me down with baby ads one week. From newborn's clothing to pampers ads. I have never ordered the like and nothing in my immediate future trends that way. When it is working I tend to see more books than anything else on the sleep screen.
