They're not wrong, sometimes you do need a "real computer". I cannot imagine trying to do my work (software development) on an iPad, that would be real torture.
EDIT:// I'm getting a little bit of shade for this comment so I want to clarify a few things. I like the iPad, I think it's a great product for tasks well suited to its form factor.
Tasks like reading a book, watching a video, playing a game. I also think it's good as an auxiliary device within a larger creative process.
However there is a lot of creative things that you can't do entirely on the iPad. Too often there comes a point in the creative workflow on an iPad where you need to take the file you're working on to a "real computer" to accomplish something that the iPad can't do.
The biggest weak point is integration. For example lets say I'm making a website. I'm coding it, HTML, CSS, Javascript. I'm also designing parts of it in Photoshop CC and I'm also testing it in various browsers.
I can't do that on an iPad. Firstly all the browsers on it use Webkit as the browser engine. Mandated by Apple. So I can't test what I make in multiple browsers on the iPad itself. I also can't easily make stuff in Photoshop and then import that into my website. The ability to edit things and upload them to the websites server is difficult on the iPad.
And as for code editors, it's difficult there too, the workflow with lots of different files in lots of directories does not lend itself well to the iPad. The files app isn't very good.
This is just one example but it's the same for video editors, image editors, music creators. There always comes a point in the workflow where you need to do something that the software is too limited to do, either the apps don't support the same file formats or their capability is not at the level of traditional desktop class software.
I have a friend who records some of his music with his iPad but he doesn't "edit" what he records on it, it's just not got the software for his level of work (professional artist). Of course he has to take it to his Mac to finish it up and to get his unique sound on the music (it's mostly electronic songs).
I have another friend who is a comic strip artist. She draws most of her stuff now on her iPad Pro with the Apple Pencil but similarly she has to take what she makes to her Mac to be able to finish it off and upload it to her website. She told me before she can do this on her iPad but that it takes too long and it's to quote her "annoying". She loves drawing on it, but once she's done she wants nothing to do with that device for manipulating the end result, authoring it on her site, it's just not as good at that stuff as her "real computer" etc
And I think most of you here know that, if you've used an iPad you have experienced the same things I'm sure. There is a lot we take for granted on traditional computers like Windows and macOS that is not there on the iPad and we miss it. The multitasking on the iPad has gotten better over a long period of time but it's still nothing as good as the "real deal" so to speak on a "real computer".
As usual Apple is competing with themselves, macOS is so good. Pretty much every review of the recent iPad Pro's I saw harped on this fact, yeah it's great hardware but it's hamstrung by so-so software (from a creative professional standpoint which is what iPad Pro's are intended for).
