The MacBook Pro, just as a powerbook before it, has a very clear design goal: to be the most powerful mobile computer within particular given (rather high) portability constrains. Put differently, its a jack of all trades portable (focus on portable). As such, the compromises haven't changed since last twenty years...
One can argue of course whether this goal is still (or ever has been) reasonable, or whether Apple is missing a significant chunk of the target market (and that would certainly be a very interesting conversation!). But the thing is, the MBP today is exactly what it was 5 or 10 years ago — the thinnest and lightest laptop in its performance category, while also having the best battery of its performance category.
And finally, I think that yes, it definitely achieves its goals (speaking specifically about the 15" model here). It comes with fastest shipping CPUs right now in the mobile market (I don't really know how it is supposed to deliver more power at this point) and its battery life is better than any comparable computer, while being thinner and lighter. Unless you speak about GPU power of course, then yes, there are certainly better choices.
