I don't know which shop the OP bought his NAS from, but....

Take a look at the reviews posted on compusa.com and circuitcity.com (both seem to be run by the same company now). I don't trust them anymore. It's hard to find a product with less then 4 stars. Often the same products are reviewed less favorably on sites like Newegg.

You could save the online bills to your computer. Many of them are available as PDFs. But, yes, it requires a certain discipline on your part rather than just having them show up in the mail.

I also agree with other posters that companies don't generally do this to go "green", but to make a buck. That is why T-Mobile's plan sounds more offensive.

Yes, I find it interesting that Americans get all fired up about privacy when a camera catches them running a red light - fired up enough to call their lawmakers and cause a 117-3 vote to ban the evil "privacy-invading" cameras.

But when their own government spies on their phone calls and emails with no warrant or cause, the response is a yawn and "Well, I have nothing to hide so why should I worry?".... Which begs the question: what are you hiding in your car then?

Seriously, look at your virulent response to red light cameras and the relatively quiet ease with which you have let your government spies get away with breaking the law.
