I don't think it will stay that way. I think in a couple of years market forces, tech advances, and infrastructure improvements will make wireless data plans much cheaper (per gigabyte).
On the other hand, our phones and pads will be more powerful and more data hungry, so we'll pay about the same as we do now. We'll just get more data for the same money, and we'll get it faster, and in more places.
If you're nostalgic for 2005, when using FaceTime on your phone didn't cost an arm and a leg, remember that in 2005 you probably weren't streaming video on your phone.
