Please don't. You have yet to make a point and have only shared what does not work for
you.
Audio and Video Editing
I can edit video and audio with my iPad Pro
Coding (github/subversion)
Don't have a need for this so this does not apply.
External monitors
I use my iPad an an external monitor all the time.
Virtualization (running different OS)
Don't have a need for this so this does not apply.
Photo editing
I edit photos all day long on my iPad pro
External devices
I can connect to external devices with my iPad pro
Ethernet Requirement at some locations (corporate settings)
I can connect to Ethernet with my iPad Pro
External video ports
Don't have a need for this so this does not apply.
Sd card slots
I can use SD cards with my iPad Pro quite easily.
USB
My iPad can do USB 3.0
Full application versions
No need for full versions when the APP counterpart can create just as well
Screen hinges
Why would the iPad need this? If it's important there are plenty of keyboard combinations that will give you a laptop set up with the iPad.
Docking stations
I can dock my iPad Pro
Applications not on the App Store/unavailable.
Irrelevant
Printers that don't support AirPrint (like at work)
Use a wireless bridge
Seriously, have you ever used an iPad? I am having a hard time believing that you own one.
