The people who review gadgets generally aren't the people who buy them. After all, whom would you hire to write your tech column, Average Joe Consumer or someone with advanced technical skills? Exactly. So tech reviewers tend to be devotees, the people who get sweaty-palmed at the thought of 64-bit addressing and multiband radios -- not members of the target audience, the 300 million who will actually spend money on these things. That's why tech blogs often savage easy-to-use products that become huge hits (the Flip camera), but adore more technical products that would overwhelm normal people (Linux).
