An ethical, focused content site with well-targeted ads?

There's not much really good information out there for a naive smartphone buyer-- reviews cover incremental improvements in technology and arbitrary lists of pros and cons that don't really touch the issues of what makes a particular phone good or bad for a potential buyer. And, after a phone is bought and a contract signed, there's not much to support a user who's got a phone and not much practical information on what they can use it for. Here's the idea: a site that does more than review (or aggregate reviews)-- a site that guides a potential smartphone customer through their options and lays out the real differences between one $100 Verizon Android phone and another.

Beyond that, people who buy smartphones don't get much support from their carrier or their phone's manufacturer after the contract is signed. Most phone buyers aren't checking out appbrain and browsing their phone's app store. This site would offer straightforward ways for people to get real utility out of their expensive hardware.

The core of the content, alongside links to others' video reviews and so on, would be a few paragraphs dealing with practical considerations in plain English for the non-technical user, for phones, apps, carriers, and technologies. The value added is a distillation of the issues that a technical consumer can get elsewhere. Mainstream journalism is lousy for helping people gain useful understanding of issues like this, and the kind of person searching for help is also the kind of person likely to click on very well-targeted ads about the products that they're now well-informed about.

Do you thing there's enough value here to make a site along those lines? Is there enough money in targeted phone and accessory ads to make it worth the effort to build a trustworthy site that ranks highly for http://www.google.com/search?q=what+smartphone+should+I+buy ?
