Productivity !== coding. Coding is a subset of productivity, but most jobs do not require coding.
I get that you want this to be something else, but a lot of people are incredibly productive on iPads today, and adding the ability to mirror your MacBooks screen means that this platform absolutely has a future in productivity.
HN has a lot of this attitude — “I can’t code directly on it so this is a toy” — and it’s always a laugh for me. There’s … other people? Who want to do other things?
