I don't know if I should get real racing 2 for the iPhone 4s or the iPad 2. The thing about the iPad 2 is that it's my school's and they're taking it back at the end of the school year and returning it when school resumes. Anyways, which is better? What's more fun to play on? The thing I love about the iPad version is the big screen but the game is optimized for the 4s. Also, I have my iPhone with me at all times. Not my iPad. Oh and I only have $1.87 left. And if not this game for the buck, any better ones? Thanks
