Customer Reviews, including Product Star Ratings help customers to learn more about the product and decide whether it is the right product for them.
To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyzed reviews to verify trustworthiness.
I enjoy this system and love the upgrades over the old PSP. I'm not currently using the 3G service but I like to have this model in case I ever change my mind. But for others would be fine to save the extra money and just get the wifi only model.
