x-Plane is awesome. Graphics are good, runs smooth on the iPad 2, and takes full advantage of the gyroscope. There are tons of planes to choose from, fully customizable weather situations, can also change the time of day. The one down side is the map areas are kind of small. For example you can't fly from New York to Chicago. You can pick NY or Chicago and many others areas and fly around that area, which are rather large. Not a huge draw back by any means. Also you can fly the space shuttle and for an extra 5 you can fly the apollo missions. The response of the plane or helicopter is very sensitive so one does not have to move the ipad around a lot to get the plane to respond. It took me a few days to get used to how much or little I had to move my device. Defiantly worth the 10 or 15 bucks. I also got a co-worker to buy this for his iPad 1 and he didn't have any complaints about how it ran with the A4 processor. He did suggest to kill all the other apps running in the back ground for the best experience.
