ARM Windows will only be the Metro version with all the isolated processes, etc. While Win x86 might have that, it shares nothing else with the traditional Windows model and is it to all intents and purposes as different as OSX and iOS.
I really don't see the problem with this if people don't have a problem with iOS only allowing Safari as the default browser.
