Gad you’re a robot. I own two iPads, including and iPad Pro with an Apple Pencil. I have also developed for iPad, and worked for a company that - in addition to workstation software - invested in developing an iPad version of their software.
In other words, I’m knowledgeable with first-hand experience, and I’m objective. I recommend backing away from the Cupertino Kool-aid…
Then you aren't really using them to their full capabilities. It's the kind of thing I see non-users come back with when they are challenged.
What were you developing for the iPad that you've never mentioned it before? What kind of "Workstation software" would you desire to move to an iPad if you truly don't think they are capable? I regularly access my file system on my Mac and iCloud from my iOS devices. Don't you? Or weren't you aware of that capability?
Adobe has just completed announced a fully functioning Photoshop for iPad. . . it will be out next quarter. That requires a lot of horsepower and file systems. Just because you don't seem to be aware of the improvements does not mean they are not there.
