I have used this theme so many times as it is still the easiest to customise as a developer, whilst being the easiest to use and understand by users.
I test the newer 2013 to the latest 2016 themes but keep coming back to 2012 theme, it is just one of those 'got it right' WP themes.
I just hope the WP developers continue to update 2012 (now v1.9) as they continue to update and develop WordPress.
