I really don’t think it needs oled or thinner. Oled risks burn in (I say as I have an oled desktop monitor without burn in, but I worry about it) — though perhaps Apple can figure that out (micro led would be great though). As for thinner, it’s pretty dang thin already. I’d rather more battery in the 14” and be a little thicker, honestly.
Yeah, tandem oleds are pretty rad. And worst case you just hook the mbp to an external display. I shall acquiesce to oled.
