Still nowhere near as bad as Rogers' outrageous prices in Canada. $60/mo for 500MB of data? No thanks!
We're becoming an embarrassment, but at least people like Michael Geist are fighting:
If you're only using the basic built-in apps, like email, web, and maps, and you buy all Apps over your Cable/DSL line at home and install via iTunes, you'll probably not go above 500MB.
But once you throw multi-media into the mix, and buying apps over the wire, it's a different story. 500MB becomes quite tiny.
