Having worked in many graphics roles for 20 years, I have never heard of a professional wanting to use an iPad for their work, yet this thread is full of people claiming the iPad is some artist dream tool. It is not even close to true.
While you may not have seen it, the number of professionals using procreate on the iPad Pro is significant.
you are missing thr point - can they use 'Only' iPad?
Who said anything about only? The article is about using iPad only specifically for travel. And the parent was discussing iPads in general.
Procreate is iPad-only. Nobody uses iPads because they like iPads. They just like that one software. They would much prefer use it on a Wacom or Xenselabs device, though.
