Knowing it might be OK, the horrible part is actually programming in that environment. It is totally locked down, you have to buy certificates and sign your applications and stuff. Without that, your application will be almost unusable (unless you only use the games APIs, which can't do much except storing high scores). Even saving a file to a directory turns into busywork for the user, as the run time system will ask for every single directory on the path if it is OK to access it... It is a bit more liberal with actions that might cost you money like dialing, sending text messages or establishing data connections (it will ask you only once), but it is still annoying. It is a trusted (by the network operators, not by you) computing environment.
