You just missed out on the popcap humble bundle.
Dang it! I actually like the Popcap games. I'm going to have to get on the mailing list or something.
Back on topic.
Mine is still a pile of wires but.... my touch screen isn't used to play games. Except for the Popcap stuff

I don't particularly care for the touch games. On mine, the bulk of configuration options is handled via touch screen. For example, instead of DIP switches on the board, configuration options is handled via the touch screen. There are other duties handled by the touch screen as well as a simplified keyboard input for basic text entry. Complex programming is handled through external tools (as it should). The FE is customized. Right now it's fugly as hell because I'm focusing on the hardware and I plan on changing out the touch screen anyways because the wife wants it back.
