Think what is throwing us all off here is the term 'Pro'. For years, it has meant the absolute top of the range notebook with the latest specs, that could be maxed out in every way possible. A desktop replacement for a Pro, like me, a developer that need to run several virtual machines, application, database and web servers, development tools and what not.
Do I need better battery life and a lighter and thinner machine? Sort of, yes, I will take it if I can get it, but it is not top of my list. Its nice to be able to work when im "between wall sockets", but I need 4-5 hours tops on battery. Do I need 32gigs of RAM? Yes Please. Even if it shortens battery life? Yes please. What if I could have a setting in the System Preferences for "use only 16gigs when on battery"? I would be thrilled.
I would at least like to have the choice and not have Apple make the choice for me. The choice that longer battery life is more important to the sort of Pro I am than raw power.
Sadly, today it seems that term 'Pro' just means 'Top of the Apple range' and no longer 'The most powerful, and above all, usable laptop there is".
