I'm approaching 50 and got prescription glasses for the first time last year, and I already need new ones. The 14.2" displays feel claustrophobic to me now. I'm either straining my eyes leaning in close because the text is too small, or I've got everything sized appropriately but it feels like I'm looking through a magnifying glass. There's no goldilocks zone. As far as MacBooks go, the 15.3" Air and 16.2" Pro are my only comfortable mobile options.
