I also think it's a great idea, to use the download capabilities of the phone! however,I know few people who actually are able to browse on their laptops through a cellphone connection,let alone an e-reader.
I myself have difficulty enabling the internet on my phone, and like mentioned the price is just way too high. Besides anything non 3G (like eg standard data transfert through cellphone signal) costs about $1 per minute @ a speed of like 112kbits/sec?
that's less than 13kB/s.
I remember I bought a game in a store for my cellphone a while ago, which costed me $11, and $4 to register (enable) it via the internet.
That's not going to convince me to ever buy another game again on my cell.
Ever since then I stopped using my cell as an internet device.

So when prices drop to an equivalent of home internet (say either $24 per month with same speeds, or price adjusted relative to the speed,options of one time internet instead of a monthly subscription, or just like calling tariff per minute) I might consider using a service like that.
