I bought a 64 Gb iPad Pro 11" a couple of weeks ago. I have time until January 8th to decide if I want to upgrade to a bigger storage model. Sadly, the next size up is 256 Gb (no 128), and that's $ 200 more. I am worried that I will run out storage soon. I shouldn't because my main use for it is to draw and illustrate, but somehow it's already 1/3 full. Which storage size did you choose? Are you regretting what you chose? Thanks for any info!
