It's the natural way to view website on the COMPUTER. This is not a computer, it's a phone. Sites are designed to be thin in width and long with content (because of so many different resolutions on computers, the industry standard is 940-960px), making it an obvious fit for a portrait phone screen (iPhone auto-resizes content, and developers can also add META tags that throw Headers on the page that tell the content to scale if viewed on a device).
I hate having all that white space on either side of the page on a wide computer screen anyways.
Matter of opinion, I guess. But your original issue won't happen if developers just code their sites correctly, with expanding widths, not heights.
No, you are wrong. Every website is better in landscape mode.
I have perfect vision and I still can't fully see most websites in portrait mode without zooming in a big. Clicking on links is extremely hard that was as well.
On the other hand, in landscape mode you can read most websites just fine.
There's no argument whatsoever...

Score one for a larger sized option...
just a note as well... 1280x720 @ 4.6 inches is STILL retina quality PPI (316)
Yeah, so we should expect Apple to model a phone around a person with bad eyes and no correction
Crazy talk...
