No, it wouldn't. The user expects a fully functional phone out of the box, complete with web browser and mail client.
otherwise why allocate disk space to be read only and have apps on it people might not want? (as far as user experience is concerned)
i meant they can maintain an app store experience without the bottlneck of downloading expected apps on day 1. instead of downloading and using data an wasting time, it would enable the app. so its the same "opt-in" experience as downloading but with benefits
