Anecdotal side note, but when I was working on a startup in some industry, we found that our largest competitor by an order of magnitude had a navigation bar at the bottom in their mobile app, while everyone else in the space used the hamburger menu. The experience made it seem like this is common knowledge at the higher levels of app design.
Even Apple has come out and explicitly spoken against the hamburger menu as a design element for iOS apps, and instead recommends tab bars.
Definitely room for an actual menu there.
Either way, a hidden hamburger menu makes 0 sense on a desktop environment anyway, no matter how much space you have.
Wait what? That's tiny for a screen, but not for a (resizable!) browser window. Here's a shout-out for folks like me who run browser windows side-by-side.
The web works better when site designers try to exert less control over it. Who are you to tell me how wide my browser window should be?

Most of those visitors are likely coming from HN, a community of people who are more likely than most to have multiple monitors. For the record, I multi-monitor at all my stationary worksites. But I don't carry external monitors on planes, airports, coffee shops, etc.
Bootstrap, for instance, uses 992px as the low end of its "large" media query, which is intended for desktops.
