All these years I've wanted a lightweight 15" (or 17") MacBook/Air but Apple insists on segmenting the larger laptops at more expensive prices. Apple won't even offer a 15" MBP without the dGPUs now.
It would weight like a similarly-sized coffee-table book, you'd need a cart to drag it around.
But yeah, overall Apple should give us more options. It was fine before with dedicated lineups - Air for battery-life and portability, Pro for ultimate power. The current lineup makes both segments pay more while giving them stuff they don't need.
I would also settle for a battery pack which charges the MacBook at full speed over USB. I know the latest one charges from battery packs, but they can usually provide 15-20W, so it's a bit from the charger's 65 or 85W.
Apple should simply offer two lines of laptop:
11"/13"/15" MacBooks optimized for thinness
13"/15"/17" MacBook Pros optimized for power
