An iPhone app or a computer game? Which should I choose?

[Mercedes]

I am looking to create a video game and was wondering whether to go with an app or a computer game that can be brought on a disc?
Both would earn me a small amount of money, considering that I'd have to sell the product for a very, very, very small fee

Well what would you choose if you had the choice? Thanks in advance

Computer game, but if youre using an engine you can make game available for different platforms with a little effort
