This again. No he’s not wrong. The professional applications of an iPad of any variety are limited compared to laptops and desktops. The iPad is very limited in its power because of a poor thermal envelope and requirement to run on battery with all day battery life. It throttles to hell and has a ton of software limitations, including extremely limited multi-tasking (e.g., max 4 windows on a screen), can’t drive multiple monitors, etc.Except the iPad has plenty of use by professionals, so…
People understand you fine, you’re just wrong.
The iPad is good at being portable, but cannot match the power and input precision of laptops and desktops that many professional applications require: the iPad’s software is designed for meaty fingers and even the mouse pointer is fat… laptops and desktops running a desktop operating system with a bitmap screen have mouse point precision to just 1 pixel.
It’s not to say that the iPad can’t be used for professional purposes but that is a short list from my experience and what I have seen people do.
