Firefox dockers are amazing. I have one running on my home network. I use it to access my router settings when I am away from home.

Iirc, sesfile stores data in a database. So no simple FS.

If you want to download cracked apps and torrents avoid the iPad.

That said, I love my iPad. I have a number of pay-one-time apps that I use and I have a linux server at home for torrenting. I stream it all to the TV and occasionally to iPad. You see, iPad (iphone etc) are not made for data storage.
