It's clear that some "professional" work can be done on an iPad. Depending on your use case it might even have some advantages compared to a desktop or laptop.

It's clear that some "professional" work can be done on an iPad. Depending on your use case it might even have some advantages compared to a desktop or laptop. But for the vast majority of cases the iPad equivalent, if it exists at all, is seriously underpowered compared to the desktop options. And there are some fundamental reasons why I expect it to stay this way. Mainly that touch is a very low resolution input mechanism but also that Apple has utterly failed to create a healthy market for sustainable professional software businesses.
