In terms of processor an iPad is a capable system. In terms of os is just a toy OS (a good one). with a lot of limitations:


- Apps are sandboxed (no access to filesystem outside its own directory)
- System calls are not available. You need to adapt the software you want to port or use a drop-in replacement (like https://github.com/holzschu/ios_system)
- running interpreted code is forbidden. Code must be compiled in (that would mean no plugins!!!)
- qtwidgets is not optimized for a touch device. Need to rewrite the whole UI using UIkit or QtQuick.
