One part of my income I make as a IPhone developer so let me tell you, deploying on IPhone/Ipod is pain. Its very likely that your app is rejected by Apple because of the limited use so you have to deploy on your own. With the developer account you can only deploy on up to 99 devices and the app is time limited, cant be started after some months. Without it (and a Mac) nothing. You already suggested game handhelds so possibly a Dingoo A320 would be enough. Input is limited to joypad and some buttons but for a simple multiple choice test its enough. Results could be stored on miniSD card. The Dingoo costs around $60-$80 The next would be a GPH Wiz which offers pen input, its the successor of GP2X, setting you back with $120-$140 Or get one of these for $99 with keyboard http://www.engadget.com/2010/03/15/qi-hardwares-tiny-hackable-ben-nanonote-… Cheers, Malte -- ---- media art + development http://www.block4.com follow me on Twitter: http://twitter.com/herrsteiner or face the book: http://www.facebook.com/herrsteiner
