I have several terabytes available multiple on line storage accounts, but I still keep most of my good stuff on my iPad. My iPad goes everywhere with me all around the world and I like to have extensive business files, financial records, technical manuals, music and book libraries, manuscripts published and in progress, and much more material I enjoy. Right now it all fits on a 512gb Pro and is readily available without the need for the internet.
I choked at paying for the 1 tb version but will definitely get the maximum available when I upgrade in a few years.
