But the days of 10 hour batter time are over. Regular use on Macbooks is now around five hours and will continue to fall in future versions.
Professional doesn't mean power hungry number cruncher as some people seem to understand it.
A doctor or a lawyer is also a professional.
As for designers and their Adobe products, Adobe would probably release an ARM version pretty fast.
Nobody? Besides the great sales whenever they put out lighter models (the Air, which was booed for not having high cpu, enough connections, etc, Macbook, the same, etc), how's that for "somebody":
"I’m have to admit being a bit baffled by how nobody else seems to have done what Apple did with the Macbook Air – even several years after the first release, the other notebook vendors continue to push those ugly and clunky things. Yes, there are vendors that have tried to emulate it, but usually pretty badly. I don’t think I’m unusual in preferring my laptop to be thin and light. (...) I’m personally just hoping that I’m ahead of the curve in my strict requirement for “small and silent”. It’s not just laptops, btw – Intel sometimes gives me pre-release hardware, and the people inside Intel I work with have learnt that being whisper-quiet is one of my primary requirements for desktops too. I am sometimes surprised at what leaf-blowers some people seem to put up with under their desks. (...) I want my office to be quiet. The loudest thing in the room – by far – should be the occasional purring of the cat. And when I travel, I want to travel light. A notebook that weighs more than a kilo is simply not a good thing (yeah, I’m using the smaller 11″ macbook air, and I think weight could still be improved on, but at least it’s very close to the magical 1kg limit)"

Apple keeps pushing the limits despite annoying some of their customer base. And often times, the bet pays off in the long term - but not always. In the case of battery life, the tech hasn't caught up enough to make it not a problem for customers yet. Example: I have a battery case on my phone that looks like crap.
The Macbook Pro is around 50 Wh IIRC, which means if you replaced it with the most expensive cells I use it'd cost $17. And although you do pay more for different cell form factors (typically a decent amount more for flat batteries) the enormous scale that Apple operates at means there's no way the batteries are going to be a price concern no matter their size.
