Here is a nice comparison. Buy a mobile device and try to use the standard developer tools to put Hello World on it. Android: Download Eclipse (Windows, Linux or Mac) and the Android SDK (Windows, Linux or Mac) - no accounts or registration needed for either of these. In your phone menus enable development and connect via USB. In Eclipse make your hello world project, and hit Run or Debug. Enjoy. Apple: You must buy…
They might sell a few more Mac desktops this way but I can't see it being a large number in the grand scheme of things.
One of the reasons I bought an Android instead of an iPhone was because I can develop for it using the computer I already have.
