>...and so is harder to develop and support for than the iOS machines... Harder to develop because you can use the programming language and runtime of your choosing, including the exact same APIs that are on iOS, or harder because you don't have to cross-compile your app for an embedded platform and test it on a remote machine whose internals you aren't allowed to change or inspect? Maybe you meant harder because there's no convoluted chain of constantly-expiring certificates needed for testing and deployment, or because you have far more RAM, disk space, screen space, and CPU cycles available, or because you can run as root or even in kernel mode to extend the OS in ways that Apple hadn't imagined instead of playing along as their dancing promotional puppet app, which they can kick to the curb on a whim? Or maybe you meant it's harder to support because users have to drag an icon (which they received from a web site in a single click) into their applications folder, instead of thumbing through 200 seemingly-identical app listings with terse descriptions and then fumbling to enter the same iTunes account password for the 90th time, re-agreeing to yet another slightly different revision of a 28-page-long terms of service and then going back and entering the same iTunes account password because iOS forgot you were actually downloading an app? Ah, of course, now I see what you mean.
