xopianoi on "Automattic annual themes broken on mobiles??"

Hello,
I expected Automattic's annual themes (tested twentyeleven-twentythirteen) to be superior in terms of their basic function, typography etc. but I've noticed that they all break on mobile devices (tested on iPhone 4 and Samsung Note 2). The content gets squished all on the left side, leaving most of the screen blank.. The search field covers the middle of the header.. What gives, Automattic? Could you please update these themes with a fix?
Thank you.
