The author writes that there is way too much connectivity, and hard to escape it (except for a plane ride, which he thinks is awesome.) I think that's an argument FOR offline web apps, and FOR self-control.
but being unable to escape connectivity makes useless for most users offline web apps...and i think having to use offline web app (a term that really sounds wrong) would just add frustration
No; people just need to take control of themselves and use offline web apps or desktop apps when they want to work on just one thing without distractions. Plus, the battery is going to last much longer for both phones and laptops that way.
