I don't understand why it is legal for Microsoft (AND Apple) to do this! How is this different from what Microsoft did with IE vs Netscape? Why doesn't this violate anti-trust or competition laws?

What monopoly are they abusing? iOS has something like 30-40% of the mobile marketshare and Android is a strong competitor. The restriction is only in place for Windows RT apps, of which Microsoft has a rather negligible marketshare of the tablet market.

It doesn't violate anti-trust laws because you have a very viable option of using Android or any other tablet OS.

The restriction against using browser engines other than IE's Trident applies to "Windows Store Apps" for desktop, too.

Mozilla and Google managed to claw out a half-hearted concession for the browsers themselves on the desktop (though not RT), but even then the other restrictions that mbrubeck noted still apply: the browser needs to be installed outside the Windows Store and only the default browser is allowed to present a touch interface. I'm not sure what purpose is behind the latter restriction, other than making switching or experimenting with browsers slightly more of a hassle.

IIRC there is no such rule in Windows Store (http://msdn.microsoft.com/en-us/library/windows/apps/hh69408... ), just there is no browser engine which would satisfy technical requirements of sandbox (no executing generated machine code means no JIT, all GUI must be implemented trough WinRT APIs or DirectX and probably many others).
