AFAIK, all Microsoft apps have been written as "asynchronous message-passing object soup" since sometime in the mid-90s. Also, with the right software you can run a large app over a distributed architecture like this without having to explicitly modularize it to fit the hardware's quirks (see, and especialy, for example).

But that isn't especially relevant, anyway. I was talking about programming techniques for existing PC hardware. Obviously, radical changes in hardware can require equally radical changes in programming methods.
