Dude.
Seriously.
Magazine publishers and/or Amazon are obviously not going to pass on cost savings to you.
They don't do it for wifi only customers. They don't do it when the royalty rates swing 40% in favor of the magazine publishers. They don't do it when they increase the royalty rates for self-publishers. They don't do it for people who only use an app rather than buy a dedicated device. They don't do it when they renegotiate the cell service contracts.
By the way, 10p per mb is the cost they're charging the
publishers. It has almost nothing to do with what Amazon is getting charged by its wireless carriers. They're almost certainly treating this as just another revenue generator, and if they didn't hit the publishers that way, they'd just charge a slightly higher royalty rate or some other miscellaneous charge.
So, yet again: You would not save one thin dime, or get any extra content, if you used your own 3g connection.
Save yourself some aggravation, and worry about things that are actually worth worrying about. Like what Lindsay Lohan will wear the next time she's in court.
