Battery life is maybe the only thing on that list that has anything to do with productivity. I'll even be generous and throw in the high res external display as an added productivity perk. The rest of the things on your list are nice to have, but many of them are available in much cheaper laptops. The screen working outside in the sun is also debatable unless you're talking about the matte screen, which costs extra.

Again, I use a MBP as my primary computer and I wouldn't trade it for anything.
