I don't buy this - as an Android customer, there's a lot of apps that simply don't do what they say. Gameloft has a 3D racer called 'Ashphalt' that has great screenshots, but runs at about 10 frames a second on a current gen device. This isn't a limit of the hardware - other racers are suitably smooth - but the returns are needed to make sure you don't get scammed by something that isn't usable.
