If you hold up an iPad Pro at WDW to video the fireworks you are never gonna watch again, I’m gonna thump your skull!

You might as well be holding up a cookie sheet!

There are certain things, like files and apps, that are different on an iPad vs. an iPhone. There have been times where I was able to use a website or app, or edit a file or whatever, on my iPad where it was not possible on my phone.

I like the larger size for viewing things. I don't use my phone for much other than a phone or apps that I use out in public (car parking, maps, etc). I also have a smaller phone so it doesn't take up so much room and it fits more easily in a pocket.

It’s impossible to use word docs and actual work on a tablet?

Nothing unless you get a big one to use it to draw on, OR get a big one and use it like a laptop. They are mostly pointless.

Get a case so you don't have to hold it
