Really? I am professional scientist working in pharmaceuticals and to be honest I use crappy old computers with one core and 2gb of ram to run all my stuff at work, I would love to be able to use my MacBook pro it would make my life a hell of a lot easier. However I have used my macbook pro for study in medicinal chemistry with molecular graphics software etc it ran just fine. Professional is about what you do not what equipment you use. What about the majority of professionals your journalists, analysts, engineers etc etc etc, where small and light for portability with enough battery to last all day and enough performance to run all their apps is exactly what they want. What about the legal obligation for apple to maximise their profits for their shareholders like any publically owned business. There is no way they could justify the losses of a niche pro line that most professionals don't want anyway. The modular mac pro is coming next year. The imac pro is available in december they are producing computers for you, they are desktops the place to be doing that work, not ruining portable computers for a few vocal people who will only be happy with a 10 pound 17 inch laptop with dual gpus in sli and 64gb of DDR4 ram and a battery life of 2 hours.
