These terms are absolutely unacceptable: "We may change or discontinue certain apps or content offered in the Windows Store at any time, for any reason."

Reminds me of the Nintendo and Sega emulators in the Android market[1]. Microsoft will be more than willing to comply with takedown requests -- regardless of how legitimate they are -- if it gives them even the slightest potential to put another dime in their pocket. Why would they ever favor consumers who are locked into their devices for 2 years at a time? Anyone who thinks otherwise is delusional.
