While this is a feature that I have been longing for tremendously, and I do think that this is a step in the right direction, I think that the 10mb limit on cellular is kind of degrading. I know that AT&T's network is limited, but I find that the average podcast I download runs at about 40mb-50mb. It's not a problem for people who live and work in broadband/wifi areas, but for those like me who do neither, it's sort of a tacked on feature that can't be utilized. Now if I'm not mistaken, I believe that AT&T's data cap is at 5gb a month. So basically you would have to download over a hundred of these larger podcast on a monthly basis (which is unlikely for most people) to exceed your limit. I just hope that over time AT&T will lighten up on their bandwidth restrictions, because at this point it's crippling the innovation process.
