The Android app store certainly exists, and is doing quite well. The web is free for all platforms. Apple don't, by any realistic measure, have a monopoly on application sales for smartphones. They just couldn't - with only 25% of the smartphone market, and an app store that targets only that 25%, how can they have a monopoly on smartphone app publication? What they might have is a monopoly on the wealthy gadget consumer with large amounts of disposable income to spend on apps. I'm not, however, that Apple's clever demographic targeting, coupled with the inability of their competitors to eat into this market via fair competition, is reason to force them to change their business model.
