When developing any product, a company will make different models to cater for different markets, different market segments (by country, age, intended uses etc.). If we buy a product that is intended for different use or different segment we will be disappointed. For instance an old man like me, without much techie background buying a very sophisticated smart phone may not be able to make use of most of the features loaded to it. AND people who are not satisfied with the product are more like to rate it. So it gets more bad ratings. Example. I use a Nokia 1202 and very much satisfied with it and am not bothered to rate it anywhere.
