The decision between the two is clearly based on personal comfort, there is no correct answer, and both sizes have advantages. Still i’m finding it very hard to decide, especially since I dont get 14 days to return.
For me, as a student who reads many research papers, reading on the 12.9” and taking notes/anotating pdfs with it seems like a dream when I was in the store (especially enjoyed it being nearly A4 size, felt very natural and pleasing).
And yet, for all other use cases, around the house... sofa, bed, morning coffee
the 11” seems (to me) way more comfortable and enjoyable to use. Especially for holding in one hand for extended time, typing, or even just the general layout of many websites seems more suitable and nicer. No doubt I would enjoy it more for these uses.
So for me... I have to decide which kind of comfort I really preffer more. The one as a student or normal everyday use at home :/
