Take the following as truth: It makes sense, then, for a browser that can find both internal and external documents to be an integral part of the system--unless, that is, you regard browsers and operating systems as still basically different things, and view Microsoft as practicing vertical foreclosure under the guise of product enhancement.
Then the following statement: "The browser is a key part of the system, it would fail without one." is true, false, or inconclusive?
Answer: Inconclusive
