exactly it is a portable office work horse..
When the 17" was out, I hardly ever saw any. In a class of 180, there were maybe 2 people with a 17" MBP. 85% had 13", several 13" airs, and a few 15" models.
I don't think the 17" would really ever catch on as a "portable" laptop. Sure, you might bring it to the coffee shop occasionally, but if you are trying to lug it to class, or all over airports, it doesn't matter how strong and manly you are, it is going to wear on you.
The 17" MBP was innovated as a 'game changer', you gotta change your whole perspective on productivity and professionalism as an artist/developer/designer/gamer, because the technology enables you to expand your scope of vision and reach new horizons. It wasn't made for the average consumer at the least, it was aimed at the PROsumers and developers absolutely.
When you are a working professional in the creative and production fields, you don't expect your instrument to be slim and light, on the contrary, you prepare yourself and make space to accommodate productivity with this machine.
It is an all in own power house, so for instance when I travel by air, I make sure I get first class if it is crunch time and I have to complete major projects while on tour or going from one residency to another across many continents. I rarely use it at a cafe because that is just stupid, for me a cafe is not a place of work, it is a place of calm or socialization period with close friends, colleagues and best of all to people watch!
So you have think of the 17" MBP as not like the other pros because it is a truly professional and premium portable notebook, not a status and practical for just everyday tasks, when there are plenty of more powerful and cheaper competition out there, people go for mac because of prestige.
It isn't just a learning tool, it is something you learn to create with. It is the PRO of the pros, so there is absolutely no comparing. This isn't a thread about comparing it is a thread about absolute defining of what is ultra portable and what is ultimate portable. You can't compare sales between the notebooks because there are just more CONsumers than there are PROsumers just face reality.
So the song goes, I'm sure -- Apple is developing and innovating on a larger retina display.
