I realized I wrote my last post in the wrong thread, because it was meant to be in another thread I started about a 14-inch MacBook (not MBP) petition I wrote to Apple. My hopes about a 14 or 15 inch MacBook below 1kg belong obviously in the MB field, not the MBP field.Anyway, you'll see a new Pro design around 2020, which should be a little lighter than the one day if it's too heavy for you.
My next Mac laptop must be either a MBP with NVIDIA GPU (ie: not ultralight), or a MB with an screen larger that 12 inch. No other Mac laptop offering is going to look attractive to me. So, if it's heavier than my MBA, it must carry an NVIDIA inside. If not, it must be lighter than my MBA but with a larger screen.
I'm going to repost the mistakenly placed text in the right thread.
