That is true. Personally, I am not fond of games with a small touchscreen. This means that I neglect any games to play on iPod Touch, iPads, or iPhones, too.

There was a port of a game that I used to play for Sega CD called Vay for the iPhone, but I don't have an iPhone, and I didn't feel like the game was worth playing due to the clunky feel of the medium, anyway.
