I usually avoid mobile versions of websites on my ipad, since it is more than capable of viewing and using most websites. However, NA has two major issues:

Typing into an edit box feels extremely sluggish. There must be some sort of processing being done on every character I type. It interferes with spellcheck and autocorrect as well. It feels as though the editbox is using 100% CPU. This is an ipad air 2.

The posting dialog is huge and a fixed size, so if I am viewing in landscape mode, I can't even see what I am typing.

edit: issue 2 doesn't appear when editing a post, since it opens as a whole page instead of a modal floating dialog box. This also seems to use MUCH less CPU, as typing is not lagged. However, there is still some shenanigans with text as the iOS autocorrect doesn't fully work. It is as though it is being overridden by the site's code.
