1. How can Intel sue MS for emulator, but linux(qemu) can get way with it?
2. Why MS tries to push the emulator, when they can just port their programs (already ported to Win RT I think) and provide developers some tools to port their apps?
There are zillions of old Windows programs whose developers are long gone. They're never getting ported. The only serious way to do this is to emulate/translate old apps automatically.
This is a big difference between os x/iOS and windows/Android. On the apple platforms developers are expected to keep doing all kinds of things in response to apples directives. Nobody will do that for windows and Android.
