I've seen some bone-headed opinions on HN before but this may take the cake...

> no tabs

Brother what are you even talking about? Tabbed applications predate the WWW.

> no bookmarks

Bookmarks are not a part of web apps, they're part of your browser (Which get this: Is a native app!)

> no copy/paste

Again, what are you smoking? Try this if you're on Windows: Open the Start Menu, then type notepad. See that menu bar up at the top? Click where it says Edit. What do you think the copy and paste options there do?

> deep links are usually broken

Okay, I'll grant you this one, deep links generally aren't a thing on native apps. But a native app is a thing that runs locally on your computer. What the hell would you be linking to?

> no ability to open multiple apps side-by-side

Not only can you open apps side-by-side, you can actually open them on top of each other.

Just because you don't know how to use your computer doesn't mean this functionality doesn't exist.
