What other online products are there to sell like E-Books and iPhone apps?

I know that by selling smartphone apps and e-books can bring in a constant stream of income without you having to do much once they are created, but what other online products can I sell?

  • Will the IPhone that's gonna be released in 2019 slow down after a few years like all the other Apple products? Ever since the news that Apple has purposefully made it so their devices slowly starts working worse as time goes by I haven't bought another Apple product but I really need a new phone, I wish I could buy another phone like Samsung but I have information on my current phone for school that can't be transferred. So I have been waiting for an Apple phone that won't slow down over time, so I don't have to constantly buy new phones and waste thousands.
  • Why do people like apple products such as iphones and macbooks? IN terms of phones Androids are BY FAR the superior device and also why would you spend over $1000 dollars on a macbook pro when you can get a toshiba touchscreen laptop with 1000 gigabytes worth of storage for only $699? Seriously i would like to know.
  • Why can't I hide or delete books on the Books app on my iPhone? I uploaded some free books to read on the app and after a couple chapters wasn't interested in them. I tried to delete them and they didn't go away. I tried to hide them and they still wouldn't go away. Now when I click "edit" it greys out the delete and hide options completely. I'm aggravated because I can't get rid of them no matter what I've tried.
  • Is there any free app to view mags and books? I use both iPhone and Samsung and wanted to know if there was a app which could be used to read free books and mags.iBooks is great but it doesn't offer new books for free. I'm willing to jailbreak my iOS or root my android if needed. I can also pay for a service in which I can read all the books I want for a period of time.
