Yes, I am thinking mostly about the ease of porting the app to different platforms. This is particularly relevant to Xournal/Xournal++ as they are terrific tools, but the hardware that these tools are optimized for typically does not run GNU/Linux. If you think that finding a good Linux laptop is a challenge, try to find a good Linux laptop with a stylus. And there's nothing in the form factor of an iPad, for example.
