im going for the 12.9 inch pro. Ive never had a 12.9 inch before. I saw and tried a 2020 in retailer store shortly before preordering. it was a on a table, and looked pretty decent, while in turn the 11 looked small.
ive had a 2017 for almost 2 years now. After almost one year, i got it replaced due to white spots.
never again. i have a creeping fear that this one might get it too. at the same time, i recently got a job, soooo yea.
I had the cash ready.
also, theres the storage problem. Since i like to download stuff, ive hit the 64gb ceiling too many times.
I spent more time thinking about what colour to choose that the storage. The price leap from 128 to 256 is cheap compared to the 500~gb version.
i shouldnt have trouble now. since im a heavy multimedia user with a tiny bit of drawing here and then, a better display is a godsend. only annoyances was having to get adapters for headphones and the likes, but it should work. Ive also got my cases and engraved apple pencil ready. I didnt really need the apple pencil as such, but its a nice luxury to have for potential note taking besides drawing.
lastly theres the processing power and ram which i find i have experiencee a bit of lag of. This happens when implay a heavy game and open up a safari slide tab at the same time. limitation was annoying.
tldr:
Better screen, better storage, better processor, no white spots and hopefully better longevity.
