It's a huge deal. I use iTunes Radio and similar when I'm driving to listen to music. I get 5GB per month of LTE-speed, after which they crank me down to sad-town speeds. Previously, on months where I drove more often, I hit the cap. This means I'll not have to care about keeping an eye on my usage. You're correct about the actual change they made: letting me do something that's comparatively low-bandwidth without it counting against my high-bandwidth concerns. But for me at least, you've underestimated the benefit: I'm unlikely to need to look at my usage again or do math to decide if it's time to stop streaming. I'll just rock on.
