Not at all. You CAN refuse to log into Gmail, go to setting to enable third party apps, go off into the web and download apk's to your hearts' content from any number of sources (including the Android Scripting Environment which you don't necessarily have to get from the Market.. without rooting, even). It's possible that the Apple side of things has similar possibilities if you jailbreak them. Edit: Oh right, forgot to add the "ka-ching!" sound to the end of my posts. KA-CHING!
