A few months ago the Fling company launched a series of joysticks for iPad tablet and at that time they seemed to be a very good way to play on the Apple tablet. Probably thanks to the popularity and high sales, the people from Fling decided to make a "mini" version of the joysticks especially for the iPhone. In the image above we have such a product made especially for the iPhone 4 which consists of 2 separate joysticks that stick to the terminal with 2 suction cups each. From the image above, it seems to me that the guys from Fling missed the idea of gaming on the iPhone because these accessories take up almost half of the terminal screen and using them makes the game more difficult, I would say.
I for one would not use something like this on the iPhone because I would kind of ruin the gaming experience if I covered half of the screen, but I would be interested in using the accessory with an iPad tablet. On the iPad, we have a large enough screen to mount in such a device and play quietly no matter what game it is. Fling mini for iPhone costs $25 and can be pre-ordered by here.
