If my friend wanted to use real equipment, he'd buy it. Also, if he was interested enough, I'd just bring an extra small deck to patch out, and tell him to bring an SD card to use and take home, so it wouldn't cost him anything. As stated above, he is only interested because he's there with me anyway, so why not experiment and see what happens. It doesn't mean that much to him, other than having something to do, I send him whatever he wants anyway.
Thank you for all the responses, I did pass along the iPhone suggestions for him to look into.
