I just bought an iPod Touch. I intend to get a developer license and at least make back the cost of the device and the license... but I don't have any great ambitions of making a living out of it. At best I can hope that I come up with a simple but appealing idea in my spare time that will be catchy enough to make some good money on the App Store. I also fully intend to give away some of my work, since I'm really doing this all for fun anyway!
