Appel doesn't believe in "desktop replacements". This should be rather clear by the fact that they have never offered one in their entire history (maybe except while Jobs was kicked, I am not too aware of how the product line was then). Desktop replacements are a very niche market and they go opposite to Apple's laptop vision (a well-built jack of all trades computer that are very mobile and have full day battery life). This is at least what Apple has consistently in the last 15 years and I think its unlikely that this basic vision will change any time soon — especially given the fact that desktop replacement machines are much rarer now than 10 yeas ago.

Maybe but I am not sure why you believe this to be true. In my opinion Apple's lackluster line of actual desktop computers, with their extra long upgrade cycles, are an indication that Apple itself views its laptops to be replacements for the traditional desktop computer for a large portion of their user base.
But even putting this aside, every product line does not need to have the same ethos by fitting into "Apple's laptop vision." This is called being narrow minded and, by being so, I think Apple has walked away from a lot of more business than you care to admit. High end gaming computers, which are essentially laptop replacements in today's parlance, are a big business. People use these computers for a lot more than gaming. In fact, the MBP is such a laptop but it is being undermined by "Apple's laptop vision." I think better heat dissipation, upgraded graphics capabilities and port selection would be a trade-off most power users would accept for more girth. In fact, Apple's 16" recent size increase is an indication that Apple is beginning to realize that the MBP needs to be better -- not thinner. All I am suggesting is that Apple should consider more of a dichotomy between their mobile focused laptops and those intended to be more powerful and beyond the criteria of thinness and weight.
